Abstract
A process cartridge includes a drum cartridge and a developing cartridge attachable to and detachable from the drum cartridge. The developing cartridge includes a developing roller, a pressing protrusion and an engagement protrusion. The drum cartridge includes a photosensitive drum, a locking member engageable with the engagement protrusion of the developing cartridge attached to the drum cartridge, and a pressing member disposed between the locking member and the photosensitive drum. The locking member is pivotable between a restricting position engaged with the engagement protrusion to restrict detachment of the developing cartridge from the drum cartridge and a non-restricting position disengaged from the engagement protrusion to allow detachment of the developing cartridge from the drum cartridge. The pressing member is configured to contact the pressing protrusion of the developing cartridge attached to the drum cartridge for pressing the developing cartridge toward the photosensitive drum.
