This is an electrophotographic marking system that effectively cleans residual toner and toner additives from the surface of a photoreceptor. This cleaning process reduces ghosting problems that had been encountered in final copies produced by electrophotographic systems such as in copiers, printers and duplicators. This cleaning is accomplished by expedients such as increasing a cleaning brush bias, and by increasing the surface area of cleaning brushes used in the system. In addition, the development process is desensitized to the development of ghosting. This desensitizing is accomplished by expedients such as increasing the gap between the development roll and the photoreceptor and by reducing the AC development electrical bias.
