Abstract

PURPOSE:To supplement abrasives effectively by collecting toner, which contains abrasives and is scraped off from a photosensitive drum with a cleaning blade, at an upper position of the blade, and supplying the toner to the surface of the photosensitive drum again. CONSTITUTION:Residual toner on a photosensitive drum 1 is carried to a cleaning part D through an electrostatic latent image formation part A, a development part B, and a transfer part C, and while the toner is scraped off by a cleaning blade 14, abrasives mixed into the toner polish the surface, but the toner scraped off by the blade 14 is supplied to the surface of the photosensitive drum again by a magnet roller 15 to stick to the surface, thus achieving sufficient abrasive cleaning.
