Abstract
[Problem to be solved] To further develop a prior art cartridge.[Solution] A cartridge includes a holding movable between a first position for stably holding a second unit in a spaced position by a first unit and a second position, and a contact force receiving portion capable of receiving a contact force for moving the holding portion from the first position toward the second position to move the second unit to a developing position, when the second unit is in the spaced position. When a predetermined tangential line is a tangential line of a surface of a photosensitive member at an intersection, which is more remote from a rotational center of a charging member, of intersections between a line connecting a rotational center of the charging member and a rotational center of the photosensitive member and the surface of the photosensitive member, as viewed along a direction of a rotational axis of the developing member, and the cartridge is divided by the predetermined tangential line into sections, a predetermined section is a section in which the rotational center of the charging member does not exist, and as viewed along the rotational axis of the developing member when the secon…
