Abstract
A developer supply container is detachably mountable to a developer supplying apparatus and includes a pump portion provided to act at least on a developer discharging chamber. The pump portion has a volume changeable with expansion and contraction with reciprocation. A cam groove is provided for converting a rotational force received by a gear into a force for decreasing the volume of pump portion, a cam groove is provided for converting the received force into a force for increasing the volume of the pump portion, and a cam groove is provided for not converting the received force for operation of the pump portion. The supplying apparatus includes a phase detecting portion for stopping the rotation of a feeding portion of the developer supply container using one of the cam grooves.
