Abstract
A developer dispenser is disclosed that has a substantially enclosed rigid housing with a side wall and a pair of end walls, an opening in the side wall, and a flexible developer mover disposed within the housing. The developer mover has one edge pivotably secured to the side wall, a second edge in sliding contact with the side wall, one surface facing the side wall and the other surface facing the opening and engaging the developer in the housing. The developer mover bends flexibly about an axis parallel to the side wall to move the surface facing the side wall toward the wall and away from the opening. When developer is contained in the housing between the developer mover and opening, the weight of the developer deflects the developer mover away from the opening. In turn, the developer mover resiliently urges the developer toward the opening.
