Abstract
A developer supply container includes a developer accommodating portion configured to accommodate a developer, a discharge opening configured and positioned to permit discharging of the developer from the developer accommodating portion, and a driving force receiving portion configured and positioned to receive a driving force. In addition, a pump portion is capable of being driven by the driving force to alternately change an internal pressure of the developer accommodating portion between a pressure lower than an ambient pressure and a pressure higher than the ambient pressure to discharge the developer through the discharge opening.
