PROBLEM TO BE SOLVED: To provide a process cartridge in which a position in a longitudinal direction of a developing unit 9 with respect to a photosensitive drum unit 8 is kept in high accuracy, and which is downsized.SOLUTION: A first regulating part 26b and a second regulating part 26c are provided in the photosensitive drum unit 8, and a first regulated part 29b and a second regulated part 29c are provided in the development unit 9. At a spaced position where a photosensitive drum 4 and a development roller 6 are spaced, the second regulating part 26c and the second regulated part 29c overlap each other in a direction perpendicular to an axial direction of the photosensitive drum 4; and at a contact position where the photosensitive drum 4 and the development roller 6 come in contact with each other, the second regulating part 26c and the second regulated part 29c do not overlap each other in a direction perpendicular to an axial direction of the photosensitive drum 4. |
