  • Publication number: 20210048774
    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.
