PURPOSE:To efficiently remove residual toner on the surface of a photosensitive body by cleaning, and to obtain such an appropriate value that the high- efficiency cleaning is maintained based on a current flowing in the photosensitive body and the rubbing width and the resistance value of a conductive cleaning member as an electrophotographic recorder using a bias cleaning method. CONSTITUTION:A charge supply means 8 and an optical erasing means 9 are arranged in order from an upstream part in the rotating direction of the photosensitive body 1 between a transfer device 5 and a bias cleaning device 10, and light irradiation is performed by the optical erasing means 9 out of a charge supply area by the charge supply means 8. |
