ABSTRACT:
An apparatus in which contaminants are on-the-fly removed from an electrode wire positioned between a donor roller and a photoconductive surface. A magnetic roller is adapted to transport developer material to the donor roller. The electrode wire is electrostatically biased with respect to the donor roller to remove contaminants therefrom. The electrostatic wire bias polarity corresponds with the contaminant charge polarity to repel the contaminants from the wire.
