Abstract
A cartridge which is detachably mountable in a printer main body includes a rotatable member and a coupler to rotate the rotatable member by receiving rotation power from an external source. The coupler includes a coupler body connected to the rotatable member and a coupler arm provided at the coupler body so as to be movable to a first position and a second position. The first position is farther from a center of rotation of the coupler than the second position, and the coupler arm is to push and rotate the coupler body when the rotation power is received by the coupler. The coupler also includes an elastic member to apply an elastic force to the coupler arm in a direction in which the coupler arm returns to the first position from the second position.
