の現像装置。[Claims for Utility Model Registration] (1) A developing device for an electrostatic recording device that is equipped with a replenishment roller and an agitating section and performs development using toner, wherein the replenishment roller replenishes toner to the developing roller and the agitating section. The developing section is located below the replenishment roller, has an opening on the replenishment roller side, and has a rotating stirring member inside to receive toner, and the stirring member transports the received toner and supplies the toner from the opening to the replenishment roller. In the apparatus, the stirring member has an elastic portion, and a wall-like member is provided above the replenishment roller and on the opening side, and the toner blown away by the elastic force of the elastic portion is collected by the wall-like member. A developing device characterized in that the developing device is dropped onto the opening side of the supply roller. (2) The developing device according to claim 1, wherein the stirring member contacts a fixed member during rotation, the elastic portion is biased, and the contact is released at the opening.
