An image forming device, including: a housing; a drawer movable between an inside position at which the drawer is located inside the housing and an outside position at which the drawer is located outside the housing; a drum cartridge including a photoconductive drum and a developer roller and mountable on the drawer; a toner cartridge storing toner to be supplied to the developer roller and mountable on the drawer, wherein the drawer includes a first guide that guides the toner cartridge in mounting the toner cartridge on the drawer, and wherein the drum cartridge includes a second guide connected to the first guide in a state in which the drum cartridge is mounted on the drawer, the second guide being configured to guide the toner cartridge in mounting the toner cartridge on the drawer in the state in which the drum cartridge is mounted on the drawer.

A metal frame of an image forming apparatus including an image forming unit which forms an image on a sheet includes: a first support member which is a sheet plate supporting the image forming unit and has a slit portion formed therein, the slit portion being a through-hole; a second support member which is arranged with an interval from the first support member and supports the image forming unit together with the first support member; and a beam member which is a sheet metal connecting the first support member and the second support member to each other, wherein the beam member includes: a facing portion which faces a first region of the first support member around the slit portion; and a fitted portion which is supported by an inner peripheral end surface of the slit portion and is fitted into the slit portion in a plate thickness direction of the fitted portion, wherein a width of the fitted portion in a direction vertical to a plate thickness direction of the first support member and the plate thickness direction of the fitted portion in the slit portion is less than or equal to a width of the slit portion in the vertical direction, and wherein the fitted portion includes a hook portion which is provided on a rear surface of a surface of the first support member on which the first region is provided, includes an end surface of the beam member facing a second region of the first support member adjacent to the slit portion in the vertical direction, with a gap, and has a hook shape.

A process cartridge includes a first unit including an image bearing member configured to carry an electrostatic latent image, and a second unit including a developer bearing member configured to develop the electrostatic latent image carried on the image bearing member into a toner image, the second unit being capable of being mounted on the first unit in a mounting direction. The first unit includes a moving member that moves the second unit mounted on the first unit at a mounting position to a detachment position. The second unit includes a storage unit that stores information about the second unit. The moving member is disposed on a first side of the process cartridge in a longitudinal direction of the image bearing member. An electrode of the storage unit is disposed on a second side of the process cartridge in the longitudinal direction.

A first drawer configured to support a drum cartridge moves in a first direction between a first mount position and a first detachment position. A second drawer configured to support a development cartridge moves in the first direction between a second mount position and a second detachment position. The second drawer is located between the first drawer located at the first mount position and a cover located at a closed position with respect to the first direction in a state where the second drawer is located at the second mount position. A lock member moves between a lock position at which the first drawer and the second drawer are locked together and a lock release position at which a lock state between the first drawer and the second drawer is released. A lock release member causes the lock member at the lock position to move to the lock release position.

A cover stopper engages a cover engaging portion when a cover is located at a closed position and to restrict rotational movement of the cover toward an open position. A rotation guide contacts, from above, a rib engagement surface during rotational movement of the cover and to guide rotational movement of the cover between the open position and a relay position. An urging member urges the cover from the relay position toward the closed position. When the cover rotationally moves from the open position to the relay position, a rib and the rotation guide engage each other to restrict upward movement of the cover against urging force of the urging member. When the cover reaches the relay position from the open position, the rib and the rotation guide become disengaged and the cover moves to the closed position where the cover engaging portion and the cover stopper engage each other.

A developing cartridge includes: a casing; a developing roller; a shaft; and a cam. The casing is configured to accommodate developer therein. The developing roller is rotatable about a first axis extending in an axial direction. The shaft extends along a second axis extending in the axial direction. The shaft is movable along the second axis. The cam is movable along the second axis in response to axial movement of the shaft. The cam has a cam surface non-parallel with the second axis.

An electronic apparatus includes a first electronic device, a second electronic device, a bundled wire configured to supply at least one of an electric signal and electric power between the first and the second electronic devices, a frame member, a bundled wire guide, and a plurality of holding portions disposed at different positions on the wiring path. Each of the plurality of the holding portions includes a hinge portion connected to an upper portion of one of the pair of the side wall portions, a cover portion connected to the storage portion via the hinge portion, and an engagement portion to secure the cover portion in a closed position. The frame member includes a groove portion to which the bundled wire guide is fitted, and the bundled wire guide with the bundled wire stored is fitted into the groove portion.

A photosensitive drum is rotatable about a drum axis extending in a first direction. A frame includes a first side plate located at first end in the first direction and a second side plate spaced from the first side plate in the first direction. The frame rotatably supports the photosensitive drum between the first side plate and the second side plate in the first direction. The frame holds a developer cartridge. A lock lever is pivotable about a pivot axis extending in a second direction intersecting with the first direction. The lock lever is movable between a lock position at which the developer cartridge is locked on the frame and a release position at which the developer cartridge is unlocked from the frame.
