Developer supply container

A developer supply container detachably mountable to a developer receiving apparatus, the developer supply container includes an accommodating portion for accommodating a developer; a discharge opening for discharging the developer accommodated in the accommodating portion from the developer supply container; a developer feeding portion for feeding the developer in the accommodating portion toward the discharge opening; a rotatable drive receiving portion for receiving a rotational force; a drive transmitting portion for transmitting the rotational force received by the drive receiving portion to the feeding portion; a portion-to-be-detected for detecting rotation of the drive receiving portion; a contact surface for contacting a rotatable member provided in the developer receiving apparatus; wherein the drive receiving portion, the portion-to-be-detected and the contact are formed integrally.

A developer supply container includes a developer accommodating chamber; a discharge opening; a fluid communication path connecting with the discharge opening; a pump portion having a volume changing with reciprocation and actable at least on the discharge opening; a regulating portion configured to regulate flow of the developer into an entrance region of the fluid communication path; a movable portion configured to move the regulating portion toward and away from the entrance of the fluid communication path; an air flow path provided inside the regulating portion to permit fluid communication between the pump portion and the discharge opening; and an elastic member provided between the regulating portion and the chamber adjacent to the entrance of the fluid communication path.
