A cartridge is detachably mountable to a main assembly of an electrophotographic image forming apparatus. The cartridge includes a rotatable member capable of carrying developer, the rotatable member being rotatable about a rotational axis thereof. The cartridge also includes a coupling member provided at one end portion of the cartridge with respect to a rotational axis direction of the rotatable member, the coupling member including at least one projection and being configured to transmit a rotational force to the rotatable member. A holding member holds the coupling member, and two pins support the holding member, with each of the two pins including a shaft portion elongated in a direction substantially perpendicular to the rotational axis of the rotatable member and the two pins being disposed substantially parallel to each other.
