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. The sheet member is arranged so that the sheet member contacts the electrophotographic photosensitive member when the second unit is positioned at the contact position and when the second unit is positioned at the separated position.
