Abstract
Control to drive and stop developing roller is effected. A cartridge includes a drive transmission member movable between a transmitting position capable of transmitting the driving force toward a developing roller and a blocking position capable of blocking the transmission of the driving force to the developing roller

1-63. (canceled)
A cartridge comprising:
- a developing roller;
- a downstream side drive transmission member rotatable about an axis thereof and movable along the axis between a transmission position in which in the downstream side drive transmission member is capable of transmitting a driving force toward the developing roller and a blocked position in which transmission of the driving force to the developing roller is blocked;
- an upstream side drive transmission member capable of transmitting the driving force toward the downstream side drive transmission member;
- an elastic member for urging the downstream side drive transmission member toward the blocked position from the transmission position;
- and
- a maintaining member rotatable about an axis thereof between a maintaining position for maintaining the downstream side drive transmission member in the transmission position against an elastic force of the elastic member and a permitting position for permitting the downstream side drive transmission member to move to the blocked position by the elastic force of the elastic member,
- wherein 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.

A cartridge comprising:
- a developing roller;
- a downstream side drive transmission member configured to receive a driving force and transmit the driving force toward the developing roller;
- an upstream side drive transmission member rotatable about an axis thereof and movable along the axis between a transmission position in which the upstream side drive transmission member is capable of transmitting the driving force toward the downstream side drive transmission member and a blocked position in which the transmission of the driving force to the downstream side drive transmission member is blocked;
- an elastic member for urging the upstream side drive transmission member toward the blocked position from the transmission position;
- and
- a maintaining member rotatable about an axis thereof between a maintaining position for maintaining the upstream side drive transmission member in the transmission position against an elastic force of the elastic member and a permitting position for permitting the upstream side drive transmission member to move to the blocked position by the elastic force of the elastic member,
- wherein the axis of the upstream side drive transmission member and the axis of the maintaining member are coaxial, and
- wherein the upstream side drive transmission member is coupled to the downstream side transmission member when the upstream side drive transmission member is in the transmission position, and the upstream side drive transmission member is not coupled to the downstream side transmission member when the upstream side drive transmission member is in the blocked position.
