Abstract

PURPOSE:To eliminate impairment of a copied image by an elastic blade for cleaning a moving type electrophotographic photoreceptor, without sacrificing the intrinsic mechanical characteristics of the blade, by adding triboelectric polarity controller to the blade. CONSTITUTION:Photoreceptor-cleaning blade 5 is, for example, made of polyurethane rubber containing 3 wt. % Valifast Black #3804 as triboelectric polarity controller and blade 5 is fixed to blade holder 6 in cleaning section 3, and pressed to the surface of photosensitive drun 1 rotating in the direction of arrow a with spring 7. This contact pressure is controlled through screw 8. Toner 12 is scraped down with blade 5, carried into case 13 with recovery roller 10 rotating in the direction of arrow b by friction with drum 1, scraped down from the surface of roller 10 with auxiliary blade 14, guided into the bottom of case 13, lead by spiral roller 15 in the direction of this shaft, and contained in a container not shown.
