Abstract

PURPOSE:To perform cleaning effectively by leading the developer which has contributed to developing and has decreased in toner concentration to a cleaning means and applying the same to the object to be developed having the residual developer upon finishing transfer thereby depositing the toner on carriers. CONSTITUTION:The developer which has developed the latent image on a photoreceptor 1 by a developing means 4 is scraped away from a sleeve 8 by a scraping-off plate 13 and is conveyed by a return screw 15. Part thereof is conveyed by the feed screw to the lower part of the feed screw 18 of a cleaning means 19. It is then scooped onto the cleaning sleeve 19 to form a cleaning brush. The toner having remained on the photorceptor 1 surface is attracted to this brush side and is thereby cleaned. And the developer is scraped away from the surface of the sleeve 19 by a scraping-off plate 23 and is conveyed to the developing part by a screw 26. On the way, the toner concentration is detected with a toner detecting means and fresh toner is replenished with a replenishing means 26 and is then mixed in the developing part 4, whereby the developer is again used for developing.
