Abstract

PURPOSE:To obtain superior cleaning performance by providing a rotatable sleeve consisting of a nonmagnetic electrically-conductive material having spiral ruggedness on the surface around stationary magnets constituted of cleaning magnetic poles, conveying magnetic poles and repulsive magnetic poles. CONSTITUTION:A photosensitive drum 1 consists of a selenium photosensitive layer 1b on an aluminum base body 1c and further an insulation layer 1a provided thereon, and the thickness combining those of the selenium layer and the insulation layer is kept at, for example, 50-100mum. A revolving sleeve having a stationary magnet group in the inside is disposed opposite to the photosensitive drum by having a spacing. The sleeve 2 consists of an aluminum pipe or steel pipe of, for example, 25-100mm. diameters, and spiral grooves of 0.5-2mm. pitches are provided in 1-5 lines on the surface thereof. By applying AC voltage to this sleeve to revolve the same, the remaining magnetic toner on the photosensitive drum is removed satisfactorily.
