An electrically conductive (64) brush is used for redistributing the residual toner images over imaging surface (10) so that the toner can be more effectively removed from the surface by the developer system C. The brush is moved in a direction perpendicular to the direction of movement (16) of the photoconductive surface and is electrically biased by means of an A.C. voltage (66) such that not only is the toner dislodged it is also picked up by the brush from one area of the photoconductive surface and dropped it on another area. By proper selection of the A.C. and D.C. voltages the conductive brush can be simultaneously used for redistribution and uniformly charging the photoreceptor surface. The perpendicular movement may be by reciprocation of a brush as shown, or by rotation of a cylindrical brush with a helical array of bristles. <IMAGE>
