PURPOSE:To uniformly stir a developer receiving chamber without giving an excessive stress to a developing material by providing a reciprocating flat stirring plate on the bottom part of the developer receiving chamber formed flat. CONSTITUTION:A device body 1 has a flat developer receiving chamber 10 and a developer stirring plate 11, and a developer carrier 12 is provided near the toner discharge hole 10a of the developer receiving chamber 10. The developer stirring plate 11 is formed of a hurdle body having crossbars on an outer frame, and constituted in such a manner that it can be reciprocated along the bottom surface of the developer receiving chamber 100 and driven in the chamber. Namely, the developer stirring plate 11 is connected to a crank part C on driving side through an arm member so that it is reciprocated, accompanied with rise and fall in the order of advance-rice-retreat-fall-advance by the circular motion of the crank part C conducted by the rotation of a driving shaft. Thus, the developer receiving chamber 10 can be uniformly stirred by the outer frame and crossbars during this motion. |
