Abstract
A toner repelling stripper finger assembly is provided for stripping toner image carrying copy sheets from an outer surface of a moving heated fusing member. The toner repelling stripper finger assembly includes (a) a finger shaft having a first end for attaching to a baffle, and a second distal end; (c) an electrically conductive tip located at the second distal end of the finger shaft for contacting the outer surface of the moving heated fusing member to strip the toner image carrying copy sheets therefrom; and (d) an electrical biasing source connected to the electrically conductive tip for electrically biasing the electrically conductive tip to a desired electrical polarity, thereby repelling and preventing charged toner particles from being attracted and building up on the stripper finger assembly.
