Abstract

PURPOSE:To make cleaning effect higher by providing two cleaning means, a conductive elastic material roller contacting an electrostatic image carrying body under pressure and an elastic cleaning blade disposed behind the same and providing a destaticizing function to the cleaning means. CONSTITUTION:A cleaning device 6 comprises the 1st cleaning means 13 and the 2nd cleaning means 14. A conductive elastic material roller 15 is used for the 1st cleaning means 13 which is grounded or is held applied with the voltage of the polarity opposite from that of electrostatic latent images. An elastic cleaning blade 17 is used as the 2nd cleaning means 14. The toner stuck electrostatically on a photosensitive drum 1 after the end of transfer is first loosened through mechanical rubbing by the 1st cleaning means 13 and since the charge on the photosensitive drum 1 is removed at this same instant, the cleaning burden of the cleaning blade 17 of the later stage is decreased.
