Abstract
A cleaning device for use with transfer type electrostatic copying machines wherein a wiping assembly disposed upstream of a charging-purpose corona discharger along the direction of travel of a photoreceptor is brought into slide contact with the photoreceptor during exposure to intercept residual toner particles on the photoreceptor. The wiping assembly comprises upstream and downstream members adapted to be brought into slide contact with the photoreceptor, and a pressure setting assembly for applying individual preset pressures to the two members, the arrangement being such that some of the residual toner particles are intercepted by the upstream member and then the remainder are intercepted by the downstream member.
