Abstract:
A process cartridge having a drum cartridge and a toner cartridge is provided. The drum cartridge includes a photosensitive drum, a cleaner, a conveyer tube, a developing roller, and a developing device. The toner cartridge is attachable to the drum cartridge and is located on a side of the developing roller opposite to the photosensitive drum in an attaching direction. The toner cartridge includes a waste toner container to store the toner conveyed through the conveyer tube and a toner container to store the toner to be supplied to the photosensitive drum. The toner container communicates with a developing chamber in the developing device and is located at least partly between the waste toner container and the developing chamber. The conveyer tube extends in the attaching direction and is arranged to overlap the photosensitive drum, the toner container, and the waste toner container in a view along an axial direction.

Claim (Index 1):
An image forming apparatus, comprising:\n a drum cartridge, the drum cartridge comprising:\n a photosensitive drum; \n a cleaner configured to remove toner from a circumferential surface of the photosensitive drum; \n a conveyer tube for conveying the toner removed from the circumferential surface of the photosensitive drum by the cleaner; \n a developing roller; and \n a developing device comprising a developing chamber to accommodate the developing roller, and \n a toner cartridge attachable to the drum cartridge along an attaching direction, the toner cartridge being located at a position on a side of the developing roller opposite to the photosensitive drum in the attaching direction while the toner cartridge is attached to the drum cartridge, the toner cartridge comprising:\n a waste toner container configured to store the toner conveyed through the conveyer tube, the waste toner container being coupled with the conveyer tube while the toner cartridge is attached to the drum cartridge; and \n a toner container configured to store the toner to be supplied to the photosensitive drum, the toner container being, while the toner cartridge is attached to the drum cartridge, configured to communicate with the developing chamber and located at least partly between the waste toner container and the developing chamber along the attaching direction, \n wherein the conveyer tube extends in the attaching direction and is arranged to overlap the photosensitive drum, the toner container, and the waste toner container in a view along an axial direction being a direction of an axis of the photosensitive drum.
