Abstract: A development container includes a positioning portion and a rotation stop portion engaged with and guided by a guide of an image forming apparatus, and a longitudinal positioning portion, at one end in an axial direction of a developer carrying member. In a state where a cartridge is attached to the image forming apparatus, when a cross-sectional positioning range is defined by using a width, having one end at a point at which the rotation stop portion contacts the guide and another end at a point at which the positioning portion contacts the guide in an attachment direction of the cartridge, and a height being a width of the guide at the point at which the rotation stop portion contacts the guide or the point at which the positioning portion contacts the guide, the longitudinal positioning portion overlaps the cross-sectional positioning range in a longitudinal direction.

Abstract: A process cartridge attachable to and detachable from an electrophotographic image forming apparatus includes a first unit having an electrophotographic photosensitive member, and a second unit including a developing roller configured to develop a latent image formed on the electrophotographic photosensitive member, and a sheet member which is disposed along the developing roller in a lengthwise direction of the developing roller and contacts the electrophotographic photosensitive member to restrain scattering of developer. The second unit is movably connected to the first unit and can move between a contact position in which the developing roller contacts the electrophotographic photosensitive member and a separated position in which the developing roller separates from the electrophotographic photosensitive member.
