Abstract: An image forming apparatus includes: a photosensitive drum; a developing unit; a casing; and a supporting member. The developing unit includes a developing agent bearing member. The developing agent bearing member has an axis extending in an axial direction and defines a first side and a second side opposite to the first side in the axial direction. The casing is configured to support the photosensitive drum and the developing unit. The casing has a sidewall at a position corresponding to the first side. The developing unit is detachable from and attachable to the casing along the axial direction. The supporting member is configured to guide a movement of the developing unit in the axial direction and protrudes outward from the sidewall.

Abstract: Image forming apparatuses include: a casing; an image forming unit removable from the casing in a first direction; and plural developer cartridges. The cartridges may be attached and detached with respect to the image forming unit in a second direction that is inclined toward the first direction. Other image forming apparatuses include: a casing; an exposure device; a plurality of cartridges configured to be attached and detached with respect to the casing in a first direction; and a recording medium transport system for transporting recording media adjacent the photosensitive members in a second direction. The first direction may be inclined with respect to the second direction, and at least a portion of optical paths of the light emitted from the exposure device may extend parallel with the first direction. Aspects also relate to image forming units, e.g., for use in image forming apparatuses as described above.

Abstract: A developing cartridge that maintains a pressing condition to press a developer carrier against the image carrier is described. The developing cartridge may include a coil spring that presses the developer carrier against the image carrier. The coil spring may include a handle that transmits a pressing force to the coil spring via the contacting member. By doing so, every time the developing cartridge is replaced, a new coil spring and handle can be provided for the color laser printer with the developing cartridge attached. Therefore, a constant pressure by the coil spring can be continuously maintained. Thus, a preferable pressure condition of the developer carrier against the image carrier can be continuously maintained.
