Abstract
A developer supply container includes a developer accommodating portion for accommodating a developer, a discharge opening for permitting discharging of the developer from the developer accommodating portion, a drive receiving portion for receiving a driving force, and a pump portion capable of being driven by the driving force received by the drive receiving portion to alternate an internal pressure of the developer accommodating portion between a pressure lower than an ambient pressure and a pressure higher than the ambient pressure by increasing and decreasing a volume of the pump portion. A position of the pump portion is set such that the pump portion starts with a stroke in which the volume increases in an initial action of the pump portion.
