摘要： A process cartridge includes a photosensitive drum, a charging unit, an exposing unit, a developing unit, an intermediate transfer unit, and a cleaning unit, arranged opposite to each other along a rotating direction of the photosensitive drum in an enclosure that has an opening opposite to a developing roller of the developing unit. An extended line connecting a tangent line to an outer circumference of the developing roller and a wall of a first end of the enclosure in an axial direction of the developing roller does not intersect with a wall of a second end of the enclosure.

摘要： A toner transport screw that is capable of maintaining a smooth and stable transport function. The toner transport screw, in which a helical blade is disposed on the circumference of a rotating shaft, has at least one spiral direction reversal part formed by connecting the respective ends of a first blade part and a second blade part, the directions of spiral of the first blade part and the second blade part being in opposite directions. A passage, which allows the toner to pass through the blades in the circumferential direction of the rotating shaft, is formed in the spiral direction reversal part.
