DEVELOPER SUPPLY CONTAINER AND DEVELOPER SUPPLYING SYSTEM

摘要

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

1. A developer supply container detachably mountable to a developer supplying apparatus, said developer supply container comprising:
a developer accommodating portion for accommodating a developer; a rotatable drive receiving portion for receiving a rotational driving force; a feeding portion for feeding the developer in said developer accommodating portion by rotation of said drive receiving portion; a developer discharging chamber provided with a discharge opening for discharging the developer fed by said feeding portion; a pump portion provided to act at least on said developer discharging chamber and having a volume changeable with expansion and contraction with reciprocation; a drive converting portion for converting the rotational force received by said drive receiving portion into a force for operating said pump portion; and a portion-to-be-detected to be detected by a detecting portion provided in the developer supplying apparatus to stop said pump portion in a predetermined expansion and contraction state of said pump portion when operation of said pump portion is stopped.
