Zusammenfassung: | A process cartridge includes a developing cartridge and a drum cartridge. The developing cartridge includes: a casing; a developing roller rotatable about a developing axis extending in a first direction; and a development-side IC chip having a development-side electrical contact surface. The drum cartridge includes: a drum frame; a photosensitive drum rotatable about a drum axis extending in the first direction; a drum-side IC chip having a drum-side electrical contact surface; and a lock lever configured to lock the developing cartridge to the drum frame. The development-side electrical contact surface and the drum-side electrical contact surface are positioned opposite to the lock lever with respect to the casing in the first direction in a state where the developing cartridge is attached to the drum frame. |
