Original Abstract Submitted

A cartridge includes a holding portion movable, by movement of a developing member in an axial direction of the developing member, between a first position for stably holding a second unit at a spaced position and a second position for stably holding a second unit at a developing position. The cartridge also includes an urging portion for urging the holding portion in a direction from the second position toward the first position in the axial direction of the developing member. At least one of the first gear portion and the second gear portion is a helical gear. When the second gear portion is driven and rotated by the first gear portion, the holding portion is moved from the first position to the second position by the second gear portion receiving a force from the first gear portion. When the second gear portion is not driven by the first gear portion, the holding portion is moved from the second position toward the first position by an urging force of the urging portion.
