Abstract
A developer supply container supplies a developer detachably set in an image forming apparatus. The developer supply container includes a main body for containing the developer; a discharge opening, which is provided in the main body, for discharging the developer; and a plurality of feeding projections, which are disposed so as to project from a curved inner surface of the main body, for feeding the developer in the main body toward the discharge opening with rotation of the main body. Each of the projections is linear without being twisted, wherein adjacent ones of the plurality of feeding projections include portions, which overlap each other as seen in a direction of an axis of rotation of the main body.
