ELECTROPHOTOGRAPHIC IMAGE FORMING DEVICE AND CARTRIDGE

[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 second unit is in the spaced position, the contact force receiving portion is in the predetermined section.
