Abstract
A cartridge includes a developing roller, a downstream side drive transmission member, an upstream side drive transmission member, an elastic member for urging the downstream side drive transmission member toward a blocked position from a transmission position, and a maintaining member for maintaining the downstream side drive transmission member in the transmission position against an elastic force of the elastic member. The downstream side drive transmission member is coupled to the upstream side transmission member when the downstream side drive transmission member is in the transmission position, and the downstream side drive transmission member is not coupled to the upstream side transmission member when the downstream side drive transmission member is in the blocked position.
