Abstract
PURPOSE:To prevent the scraped residual toner from accumulating in the cleaning device including a cleaning blade by applying the voltage of the same polarity as that of the toner to the guide plate provided below a cleaning blade. CONSTITUTION:A guide plate 14 is provided below the cleaning blade 13 whose end is in contact with the generator of the photosensitive drum 1 of an electrostatic copier of dry developing system and which scrapes off the residual toner and since the voltage of the polarity opposite from that of the charges charged on the toner is held applied to the electrode 19 added to this guide plate 14, the toner particles flying by being scraped off by the cleaning blade 13 receive repulsion by electrostatic force with the electrode 19, slip down along the electrode 19, accumulate on the bottom of a case 11 and are sent to a discharge port 17 by a screw 15.
