Abstract

In the case that a developer supply container is provided with a feeding portion for feeding a developer by receiving a rotational force and a pump portion for discharging the developer by reciprocation, and the rotational force and a reciprocating force are received from a main assembly side of an image forming apparatus, there is a liability that a driving connection is not properly established between a portion of the developer supply container for receiving the reciprocating force and a portion of the main assembly side for applying the reciprocating force.

The developer supply container is provided with a drive converting mechanism for converting the rotational force received from the main assembly side to a force for operating a volume changing type pump.

Claims

1. A developer supply container detachably mountable to a developer replenishing apparatus, said developer supply container comprising:

a developer accommodating chamber for accommodating a developer;

a feeding portion for feeding the developer in said developer accommodating chamber with rotation thereof;

a developer discharging chamber provided with a discharge opening for permitting discharging of the developer fed by said feeding portion;

a drive inputting portion for receiving a rotational force for rotating said feeding portion from said developer replenishing apparatus;

a pump portion for acting at least said developer discharging chamber, said pump portion having a volume which changes with reciprocation; and

a drive converting portion for converting the rotational force received by said drive inputting portion to a force for operating said pump portion.
