Abstract
A cartridge detachably mountable to a main assembly of an image forming apparatus includes: a frame; a flexible developer bag, provided with an opening and provided inside the frame, for containing a developer; and an elastic member for discharging the developer through the opening by acting on the developer bag. The elastic member is extended from a free state by contact with the developer bag, and elastic energy accumulated by extension of the elastic member acts on the developer bag to discharge the developer through the opening.
