Abstract

PURPOSE:To eliminate toner clogging, increase toner conveying capacity and enable the sufficinet coping with the higher speed of copying by providing a ladder chain which cyclically travels in the toner recovery course. CONSTITUTION:The toners 6 scrapped off by a cleaning blade 5 along with the revolution of a photosensitive drum 1 accumulate subsequently in a toner well 8 by their own weight and are conveyed toward a recovery course 15 by a lead screw 9, thence they are dropped onto a ladder chain 14. As the ladder chain 14 travels, the toners 6 are conveyed toward a developing device 2 and taken into a toner hopper 11 through a toner discharge port 12 by a revolving lead screw 13.
