In an image forming apparatus having a housing; a cartridge including an image bearing member and capable of being attached/detached to/from the housing; a discharging exposure unit having a light source member and a light guide member, which forms a light guide path guiding light from the light source member so as to be emitted to the image bearing member, and exposing the image bearing member; and an opening/closing member capable of being opened/closed and provided on a surface on which an opening portion, through which the cartridge is inserted/removed in the housing, is provided so as to cover the opening portion, wherein the light source member is provided so as to be exposed to a surface of the housing opened/closed by the opening/closing member and be capable of being attached/detached to/from the light guide member.

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.

An image forming apparatus includes a main body housing, a drawer, a drum cartridge, an exposure device, developing cartridge, a transfer roller, and a fixing device. The drum cartridge includes a photosensitive drum and is attachable to and detachable from a first supporting position on the drawer. The developing cartridge is attachable to and detachable from a second supporting position on the drawer and includes a developing roller. The drawer includes a first guide. The drum cartridge includes a second guide. In a state where the drum cartridge is attached to the first supporting position on the drawer, the first guide of the drawer and the second guide of the drum cartridge form a developing cartridge guide configured to guide the developing cartridge toward the second supporting position on the drawer.

An image forming apparatus including a main body casing, a drum cartridge and a developing cartridge. The main body casing has an opening and a slot extending in from the opening toward an inside of the main body casing along a first direction. The drum cartridge and the developing cartridge are arranged in a second direction intersecting the first direction in a state where the drum cartridge and the developing cartridge are attached to the slot. The main body casing includes a drum guide groove configured to guide movement of the drum cartridge. The drum cartridge includes a drum protrusion configured to be engaged with the drum guide groove. A width of the drum guide groove in the second direction is decreased toward the inside of the main body casing from the opening.

An image forming apparatus includes a main body casing, a drum cartridge, a developing cartridge and an intermediate transfer belt. The drum cartridge is removably insertable into to the main body casing in a first direction. The developing cartridge is removably insertable into the main body casing in the first direction. The drum cartridge includes a first handle. The first handle has a first recess having a first hollow. The developing cartridge includes a second handle. The second handle has a second recess having a second hollow.

A process cartridge detachably mountable to a main assembly of an image forming apparatus, the process cartridge includes a photosensitive drum unit including a photosensitive drum, and a first and second positioning portions Configured to position the photosensitive drum unit relative to the main assembly; and a developing unit connected with the photosensitive drum unit, the developing unit including a developing roller, a storing means having a contact surface electrically connectable with a main assembly contact of the main assembly to communicate with the main assembly. As seen in an axial direction of the photosensitive drum, a first line segment connecting the first positioning portion and the second positioning portion with each other and a first linear line passing through the contact surface and perpendicular to the contact surface crosses with each other.

An image forming apparatus includes: a main body housing; a developing cartridge attachable to and detachable from the main body housing; a drum cartridge attachable to and detachable from the main body housing; and a developing guide for guiding attachment and detachment of the developing cartridge to and from the main body housing. The developing cartridge includes a developing roller and a developing memory for storing information. The drum cartridge includes a photosensitive drum. The developing guide is movable together with the developing cartridge between a first position where the developing roller is in contact with the photosensitive drum and a second position where the developing roller is separated from the photosensitive drum. The developing guide includes a developing memory terminal configured to be in contact with the developing memory in a state where the developing cartridge is attached to the main body housing.

An image forming apparatus can include a main body housing, a drum cartridge, an exposure device, a developing cartridge, and a transfer roller. The drum cartridge can include a photosensitive drum and a guide, and can be movable between an inner position where the drum cartridge is accommodated inside a space and an outer position where at least a part of the drum cartridge is drawn out of the space through an opening. The developing cartridge is attachable to and detachable from the guide. The exposure device is configured to expose the photosensitive drum and is located above the developing cartridge when the drum cartridge is at the inner position and the developing cartridge is attached to the guide.
