An electrically conductive brush 25 is illustrated (Figures 1 and 2) for effecting simultaneous charging and cleaning of a photoreceptor surface. The brush is constructed of alternate conductive and non-conductive segments 26 and 27 which causes one conductive segment which is being used for charging to be electrically isolated from another conductive segment which is being used for cleaning. Thus, different voltages can be simultaneously applied to each of the segments without adversely affecting the operation of the other. A single detoning roller 94 is also provided for removing toner particles from the brush, the detoning roller being positioned adjacent the cleaning part of the brush to allow for the application thereto of a lower voltage than would be required if the detoning roller was used in conjunction with a charging brush of the prior art or with the charging segment of the brush of this disclosure.
