ABSTRACT:
An apparatus and method for cleaning charged triboelectric negative toner residual particles from the photoreceptor surface. A positive bias is applied to two electrostatic brushes in the dual cleaning system or to a single electrostatic brush. The rotational speed of the single positive brush is increased, over that of the individual brushes in a dual brush cleaner, to clean charged triboelectric negative toner particles.
