Abstract
Apparatus for removing residual charged particles from a charge retentive surface characterized by a self-biasing electrostatic cleaner brush and a flicker bar. The brush includes fibers made of a bi-layer of PVDF films; one of which is PVDF covered over a conductive core. Upon bending in one direction, the fiber will generate an electrical potential which will attract and hold oppositely charged toner, which will then be released when the fiber is flexed by the flicker bar in the opposite direction.
