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.

Abstract: A method and apparatus for eliminating the accumulation of triboelectric negative toner that occurs between the cleaning edge of the cleaning blade and the photoreceptor surface. After image transfer, the residual toner particles on the photoreceptor surface are then charged to a uniform polarity using either a preclean corotron or a biased conductive blade. A UCA is used to dislodge the residual toner particles away from the photoreceptor surface. The polarity of the particles is opposite to that of the collection roll positioned to attract the toner particles levitated by the UCA onto the collection roll.

Abstract: An apparatus and method for cleaning triboelectric negative toner particles from the photoreceptor surface without the need of a preclean corotron. To remove the residual particles, a first cleaning brush, in the direction of motion of the photoreceptor, is negatively biased to remove the positive (+) toner and charge the toner particles negative. Then, the second brush, in the direction of motion of the photoreceptor, is positively biased to remove the residual negative toner particles from the surface as the second brush contacts the surface.
