Abstract
A process cartridge, wherein both in the case where the developing unit is at the contact position and in the case where the developing unit is at the separation position, a first regulating portion that the drum unit has and a first regulated portion that the developing unit has, are engaged with each other, whereby movement of the developing unit with respect to the drum unit in the axial direction of the developing roller is regulated, wherein in the case where the developing unit is at the separation position, a second regulating portion and a second regulated portion overlap each other in a direction perpendicular to the axial direction, and wherein in the case where the developing unit is at the contact position, the second regulating portion and the second regulated portion do not overlap each other in the direction perpendicular to the axial direction.
