Abstract

A developer supply container includes a developer accommodating chamber configured to accommodate developer, a feeding portion configured and positioned to feed the developer in the developer accommodating chamber by rotation thereof, and a developer discharging chamber provided with a discharge opening configured to permit discharging of the developer fed by the feeding portion. In addition, a rotatable gear rotates the feeding portion, a pump portion acts upon at least the developer discharging chamber, with the pump portion having a volume which changes with reciprocation, and a drive converting portion converts a rotational force generated by rotation of the gear to a force for operating the pump portion.
