Abstract
A cartridge frame includes a protruding rib protruding toward a first frame, a first bearing supporting one end of a photosensitive drum in an axial direction, and a second bearing supporting an other end of the photosensitive drum in the axial direction. The first frame includes a first guide rail configured to, when a process cartridge is attached to an apparatus main body, guide the protruding rib to slide along the first guide rail. A second frame includes a second guide rail configured to, when the process cartridge is attached to the apparatus main body, guide the second bearing to slide along the second guide rail. A size of the first guide rail in a width direction perpendicular to both the axial direction and an attachment direction of the process cartridge is smaller than a size of the second guide rail in the width direction.
