PURPOSE:To maintain good developability, to economize the developer and to eliminate the need for a large recovering box for the developer by mixing the developer recovered in a cleaning part and the developer to be supplied from a developing device and removing unnecessary materials from the developer by a removing device thereby regenerating the developer. CONSTITUTION:The toner sticking on a photosensitive drum 10 rotating in a clockwise direction is scraped by a rubber blade 31 in a cleaning device 30. The residual toner falls along a capturing plate 32 into a developer agitating chamber 33, where the developer is agitated with the developer fed therein through a developer circulating path 34 by a screw 35. The developer rotates in a clockwise direction and is conveyed by sticking on the peripheral surface of a sleeve 37 provided with a stationary magnet 36. The unnecessary materials on the surface of the sleeve 37 are scraped off by a rotary brush 39 in a vessel 43, and are dropped into the vessel 43 by a plate material 40. The regenerated developer is fed to a developing device through the path 34. The good developability is thus maintained and the developer is economized. |
