| 1. A toner repelling stripper finger assembly for stripping toner image carrying copy sheets from an outer surface of a moving
heated fusing member, the toner repelling stripper finger assembly comprising:
(a) a finger shaft having a first end for attaching to a baffle, and a second distal end;
(b) an electrically conductive tip located at said second distal end of said finger shaft for contacting the outer surface
of said moving heated fusing member to strip said toner image carrying copy sheets therefrom;
(c) an electrical biasing source connected to said electrically conductive tip for electrically biasing said electrically
conductive tip to a desired electrically polarity, thereby repelling and preventing charged toner particles from being attracted
and building up on the stripper finger assembly; and
(d) a control device for selectively controlling polarity electrical bias on said electrically conductive tip.
