Patent ID: 8335464

Claim:
A cleaning brush for use in an electrostatographic apparatus, comprising a plurality of individual electrically conductive fibers secured to a brush core and having fiber tips relatively remote from the brush core; wherein the cleaning brush includes: a) an electrically conductive plane between a surface of the brush core and the electrically conductive fibers, effective for inducing an electrical potential to the conductive fibers when an electrical potential is applied to the electrically conductive plane; and b) a relatively non-conductive layer electrically insulating the conductive plane from the conductive fibers; wherein the electrically conductive fibers comprise an electrically conductive core and a surrounding relatively nonconducting annular portion, the fibers are woven into a non-conductive backing, the nonconductive backing is coated with a nonconductive adhesive layer which forms the non-conducting layer, the backing is adhered to the brush core, and the conductive plane comprises a conductive layer coated on the nonconductive adhesive layer.
