Claims

[Claims for Utility Model Registration] 1. A developing container that stores a developer containing magnetic powder, and a developing magnet roll that conveys the developer to a developing section close to a photoconductor and performs development with a magnetic brush. In a developing device configured to include an auger, which is at least one screw-like stirring member that transports and stirs the developer returned to the developing container in the axial direction of the developing magnet roll,
A developing device characterized by supplying/discharging developer by rotating an auger forward/reversely. 2. The developing device according to claim 1, wherein the developer supply port and the developer discharge port are the same port. 3. Conveyance of the developing magnet roll and developer;
3. The developing device according to claim 1, further comprising means for driving the stirring members separately. 4. The developing device according to claim 3, wherein the developing magnet roll is stopped when the developer is introduced.
