PURPOSE:To prevent a developer returning means and a cleaning means from being broken owing to developer clogging by driving the developer returning means in synchronism with the driving of a developing means, the cleaner means, and an image carrier. CONSTITUTION:The toner returning means 68 is driven is synchronism with the driving of the photosensitive body 16, developing device 18, cleaning device 21, etc. Namely, while the photosensitive body 15, developing device 18, and cleaning device 21 are driven, the toner returning means 68 is driven. Toner collected according to the driving of the photosensitive body 15, etc., is therefore returned to the developing device 18 in order. Consequently, then developer returning means 68 and cleaner means 21 are prevented from being broken owing to developer clogging. |
