CLEANING METHOD AND APPARATUS FOR A XEROGRAPHIC REPRODUCING APPARATUS

摘要

Method and apparatus for moving residual toner from a photoconductive imaging surface. The invention includes the provision of an electrically conductive brush used for redistributing the residual toner images over the imaging surface so that the toner can be more effectively removed from the surface by the developer system. The brush is electrically biased by means of an A.C. voltage such that not only is the toner dislodged it is also picked up by the brush from one area of the photo conductive 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.
