Abstract:
A developing roller and a photosensitive drum are aligned in a second direction different from a first direction. A toner storage portion stores toner to be supplied to the photosensitive drum by the developing roller. A waste-toner storage portion stores toner conveyed through a conveyance pipe. The waste-toner storage portion has a main portion and a protruding portion protruding from the main portion in the first direction. A drum cartridge has a guide portion configured to guide the protruding portion of the waste-toner storage portion when a developing cartridge is being mounted on the drum cartridge. The guide portion includes first and second guides. The first guide extends in a third direction different from the first and second directions. The second guide continues from the first guide and is located closer to the photosensitive drum than the first guide is. The second guide extends in the second direction.

Claim (Index 19):
A developing cartridge detachably attachable to a drum cartridge including a photosensitive drum rotatable about a drum axis extending in a first direction, the photosensitive drum having a circumferential surface, a cleaner configured to remove toner from the circumferential surface of the photosensitive drum, and a conveyance pipe for conveying waste toner removed by the cleaner, the conveyance pipe having a discharge port for discharging waste toner removed by the cleaner,\n the developing cartridge comprises: a developing roller rotatable about a roller axis extending in the first direction, the developing roller being adjacent to the photosensitive drum in a state where the developing cartridge is mounted on the drum cartridge, the developing roller and the photosensitive drum being aligned in a second direction different from the first direction in a state where the developing cartridge is mounted on the drum cartridge; a toner storage portion configured to store toner to be supplied to the photosensitive drum by the developing roller; and a waste-toner storage portion configured to store toner conveyed through the conveyance pipe, the waste-toner storage portion having a main portion and a protruding portion protruding from the main portion in the first direction; and a guide configured to guide the protruding portion of the waste-toner storage portion when the developing cartridge is being mounted on the drum cartridge; wherein the guide comprises: a first guide extending in a third direction different from the first direction and the second direction, the first guide being located on an opposite side from the photosensitive drum with respect to the discharge port in the second direction.
