An image forming apparatus includes a drawer and a main body. The drawer includes a drawer-side electrical contact part and a socket. The main body includes a main body-side connector including: a main body-side electrical contact part; and a holder including a base, a panel, and an elastic member interposed between the base and the panel. The holder holds the main body-side electrical contact part to be movable in an intersection direction intersecting with an extension and contraction direction of the elastic member. When the holder contacts the socket, the panel moves relative to the base in the intersection direction together with the main body side-electrical contact part, and the main body side-electrical contact part and drawer-side electrical contact part are in contact with each other.

A drawer is moveable between an inner position and an outer position through an opening when a cover is located at an opening position. A waste toner conveying tube is movable in a second direction between a first connection position and a first disconnection position when a drum cartridge is attached to a drawer and the drawer is at the inner position. When the cover moves from a closing position toward the opening position, the waste toner conveying tube moves from the first connection position toward the first disconnection position in conjunction with the movement of the cover. The drawer is movable from the inner position toward to the outer position when the drum cartridge is attached to the drawer, the drawer is at the inner position, and the waste toner conveying tube is at the first disconnection position.

An image forming apparatus includes a developer container to and from which the replenishment container is attachable and detachable and which includes an accommodating portion that accommodates developer and a replenishment port, an agitation member, an opening/closing member configured to be movable between a closed position and an open position, a drive source for driving the agitation member, and a control portion configured to control the drive source. The apparatus is configured such that image formation is not possible when the opening/closing member is at the open position, and the agitation member is capable of driving in a case where the opening/closing member is at the open position.

An image forming apparatus of the present invention includes: a body; a developing cartridge having a memory medium and a developer bearing member; a tray including a frame which is movable between a housed position and a drawn-out position and has side portions extending in the moving direction and to which the developing cartridge is attachable, an image bearing member that faces the developer bearing member when the developing cartridge is attached, a tray-side metal terminal provided on the side portion and electrically connected to the memory medium when the cartridge is attached, and a tray guide portion extending along the moving direction; a body-side metal terminal that faces the tray-side metal terminal when the tray is housed, wherein the tray-side metal terminal is provided below the tray guide portion.

An image forming apparatus includes: a first guide that is provided in an apparatus housing and configured to suspend and hold a first unit including an image holder so that the first unit is movable in an insertion and removal direction; a second guide that is provided in the apparatus housing and configured to suspend and hold a second unit including a developer holder so that the second unit is movable in an insertion and removal direction; and a pedestal that is disposed on a front side in the insertion and removal direction with respect to the first guide and the second guide, supports, from below in a gravity direction, the first unit and the second unit while the first unit and the second unit are inserted into the apparatus housing, and does not contact with the first unit and the second unit located in the apparatus housing.

In a cartridge assembly, a cartridge frame is configured to limit a movable amount of a photosensitive drum with respect to the frame in a longitudinal direction of the photosensitive drum to a first amount in the case where a cover member is apart from the frame, and the cover member has a held portion held by the frame and a limiting portion configured to limit the movable amount of the photosensitive drum with respect to the frame to a second amount smaller than the first amount by contacting with a longitudinal end surface of the photosensitive drum in the case where the photosensitive drum moves in the longitudinal direction when the cover member is mounted on the frame.

An image forming apparatus to form a toner image on a recording material includes a photosensitive member and an optical scanning unit. The optical scanning unit includes an optical scanning unit, an optical box, a cover member, and a moving unit movable to an outside of the image forming apparatus. The optical scanning unit and the moving unit are arranged so that the moving unit and the optical scanning unit are opposed to each other when the moving unit is located in an inside of the image forming apparatus. The optical scanning unit is disposed so as to allow a user to touch the optical scanning unit through a space generated in the inside of the image forming apparatus when the moving unit is moved to the outside of the image forming apparatus. Between the optical box and the cover member, the cover member is opposed to the moving unit.

An operation assisting tool includes a gripper, and an engagement portion to engage with a handle of a drawer drawable from a housing of an image forming apparatus.

An image forming apparatus is provided, including a housing; a drum cartridge; a developing cartridge; a drawer movable between an inner position and an outer position; and a lock member provided on the drawer and movable between a lock position at which the lock member locks the drum cartridge to the drawer, and a release position at which a lock between the drum cartridge and the drawer is released. The lock member includes an operation portion for moving the lock member between the lock position and the release position. The developing cartridge includes a cover member that covers at least a portion of the operation portion in a state in which the drum cartridge is mounted to the drawer, and the developing cartridge is mounted to the drum cartridge.

A process cartridge is detachably mountable to a main assembly of an electrophotographic image forming apparatus. The cartridge includes an electrophotographic photosensitive drum, a developing roller, a drum unit containing the drum, a developing unit containing the roller and being movable so the roller contacts and is spaced from the drum, and a first force receiver receiving a force from a main-assembly first force applier by movement of a door from open to closed positions when mounting the cartridge and a second force receiver movable from a stand-by position by movement of the first force receiver by a force received from the first force applier. The second force receiver takes a projected position receiving a force from the second force applier to move the developing unit so the roller moves out of contact with the drum, the projected position being higher than the stand-by position.
