Abstract
A photosensitive-member cartridge has an upper registration roller, and both ends of the upper registration roller are rotatably supported on respective side walls of a casing by roller support members. Torsion coil springs are engaged with the roller support members and the side walls, and urge the upper registration roller upward. When the photosensitive-member cartridge is alone, the upper registration roller is held at a retract position with respect to a bottom wall of the casing without rattling.
