The present disclosure relates to a developing cartridge, which can be detachably installed in an electronic imaging device, comprising: a housing having a developer accommodating portion capable of accommodating a developer; a developing roller, which is provided on a lower end side of the housing, is rotatably supported by the housing, and can carry the developer on its outer surface; and a handle provided on an upper end side of the housing opposite to the lower end side; wherein the handle comprises a grasping portion, the grasping portion has an upper plate and a lower plate, an accommodating portion is provided between the lower plate and the housing, and a rib connecting the upper plate and the lower plate is provided between the upper plate and the lower plate. The technical problem in the prior art that the elastic plate in the handle is easily damaged is solved.

An image forming apparatus includes: a housing having an opening; a drawer movable, through the opening, between a housing position in which the drawer is housed in the housing and a drawn position in which the drawer is drawn from the housing; a first drum cartridge including a first photosensitive drum, and mountable to and removable from the drawer; a first developing cartridge including a first developing roller, and mountable to and removable from the first drum cartridge; and a transfer device configured to transfer toner on the first photosensitive drum to a sheet and located above the first drum cartridge in a state where the first drum cartridge is mounted to the drawer and the drawer is located in the housing position. In a state where the first drum cartridge is removed from the drawer, the first developing cartridge is mountable to and removable from the first drum cartridge.

An image forming apparatus includes a housing and a first process cartridge. The first process cartridge is attachable to and detachable from the housing. The first process cartridge includes a first photosensitive drum, a first developing roller, and a developing frame. The developing frame has a toner inlet opening. The toner cartridge has a toner supply opening. The toner cartridge is positioned above the developing frame such that the toner supply opening and the toner inlet opening face with each other in upward/downward direction. In the state where the first process cartridge to which the toner cartridge is attached is attached to the housing, the toner cartridge is incapable of being detached from the first process cartridge. In a state where the first process cartridge to which the toner cartridge is attached is detached from the housing, the toner cartridge is detachable from the first process cartridge.

An image forming apparatus includes a first unit dismountably mounted on a main body frame and a locking mechanism releasably holding the first unit mounted. The locking mechanism has a handle portion, a lock member, and a preloading member. The handle portion is on the first unit, and is movable to and fro in the mounting and dismounting directions of the first unit. The lock member is swingably on the first unit, and has a hook portion engageable with an engaged portion formed on the main body frame. The preloading member preloads the lock member in a first direction in which the hook portion engages with the engaged portion. As the handle portion is moved in the dismounting direction, the lock member swings in a second direction opposite to the first direction against the preloading force of the preloading member to disengage the hook portion from the engaged portion.

An image forming apparatus includes: a housing having an opening; a drawer movable, through the opening, between a housing position in which the drawer is housed in the housing and a drawn position in which the drawer is drawn from the housing; a first drum cartridge including a first photosensitive drum, and mountable to and removable from the drawer; a first developing cartridge including a first developing roller, and mountable to and removable from the first drum cartridge; and a transfer device configured to transfer toner on the first photosensitive drum to a sheet and located above the first drum cartridge in a state where the first drum cartridge is mounted to the drawer and the drawer is located in the housing position. In a state where the first drum cartridge is removed from the drawer, the first developing cartridge is mountable to and removable from the first drum cartridge.

A toner cartridge according to one example embodiment includes a housing having a reservoir for holding toner. A first latch-receiving shelf is positioned on a first longitudinal end of the housing and a second latch-receiving shelf is positioned on a second longitudinal end of the housing. Contact surfaces on top portions of the first and second latch-receiving shelves are positioned to contact corresponding first and second latches in an image forming device. The contact surface of the first latch-receiving shelf is positioned lower than a first rotational axis of a first drive coupler of the toner cartridge and higher than a second drive coupler of the toner cartridge. The contact surface of the second latch-receiving shelf is positioned lower than at least a portion of a first electrical contact of the toner cartridge and higher than at least a portion of a second electrical contact of the toner cartridge.

An image forming apparatus includes an apparatus main body, a process cartridge, a scanner unit, and a toner cartridge. The process cartridge is detachably mounted on the apparatus main body. The process cartridge includes: a photosensitive drum configured to rotate about a rotational axis extending in a first direction; and a development unit configured to supply toner to the photosensitive drum. The toner cartridge is configured to store toner. At least part of the photosensitive drum, at least part of the scanner unit, and at least part of the toner cartridge are aligned in a second direction in this order. The second direction is perpendicular to both the first direction and to a vertical direction. The at least part of the photosensitive drum, the at least part of the scanner unit, and the at least part of the toner cartridge overlap one another as viewed from the second direction.

An image forming apparatus includes: a housing; a drawer movable between an inner position accommodated within the housing and an outer position exposed to an outside of the housing; a drum cartridge including a photosensitive drum and a drum frame; a developing cartridge; and a pressing member for pressing the drum frame. The drum frame includes: first and second side frames supporting first and second end portions of the photosensitive drum, respectively; and an upper frame connecting upper end portions of the first and second side frames to each other. In a state where the drum cartridge to which the developing cartridge has been attached is attached to the drawer and the drawer is in the inner position, the developing cartridge is positioned between the photosensitive drum and the upper frame, and the pressing member is positioned above the upper frame to press the upper frame downward.

Disclosed is a developing apparatus including: a developer bearing member that bears a developer; a developing frame body that rotatably supports the developer bearing member; a one-end side end member that supports one-end side in an axis direction of the developer bearing member of the developing frame body; and another-end side end member that supports the other-end side in the axis direction of the developer bearing member of the developing frame body. Each of the one-end side end member and the other-end side end member is independently movable with respect to the developing frame body.

A printer includes a main body including a printing unit for printing an image, a developer cartridge for accommodating a developer to be supplied to the printing unit and removable from the main body, a releasing member provided in the main body and pushing the developer cartridge in a removal direction to move the developer cartridge from a mounting position where the developer cartridge is locked to the main body to a removal position where the developer cartridge is unlocked, and a handle provided on the developer cartridge. The handle moves in conjunction with the movement of the developer cartridge from the mounting position to the removal position of the developer cartridge such that the handle is switched from a first position adjacent to a side of the developer cartridge to a second position protruding from the side of the developer cartridge, so that the handle can be gripped.
