Claims

[Claims for Utility Model Registration] 1. A developing chamber that accommodates a developer, a replenishing developer accommodating chamber for replenishing the developer to the developing chamber, and communication between the developing chamber and the replenishing developer accommodating chamber. A developing device comprising a developer replenishment roller that is disposed on the side of the replenishment developer storage chamber and that carries developer on its circumferential surface and replenishes the developer from the replenishment developer storage chamber to the development chamber, the replenishment developer storage chamber side In this case, a developer receiving wall is disposed close to the circumferential surface of the developer replenishing roller, and swings intermittently in directions approaching and away from the circumferential surface to apply developer to the circumferential surface. A developing device characterized by having a swinging wall member that presses. 2. The swinging wall member swings intermittently in contact with a developer stirring and conveying member that is rotatably provided in the replenishing developer storage chamber and scoops up the developer and conveys it to the developer replenishment roller. The developing device according to claim 1, characterized in that:
