CORRECT BRUSH BIAS POLARITY FOR SINGLE AND DUAL ESB CLEANERS WITH TRIBOELECTRIC NEGATIVE TONERS

摘要

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 asingle electrostatic brush. The rotational speed of the single positive brush isincreased, over that of the individual brushes i n a dual brush cleaner, to cleancharged triboelectric ne gative toner particles.
