Abstract
An electrophotographic machine includes a dielectric member carrying a toner image. A biased transfer roller engages the dielectric member and transfers the toner image to an image substrate. A cleaning brush having a plurality of bristles, at least some of which are electrically conductive, engages the transfer roller. An electrically conductive housing encloses the cleaning brush. The bristles contact the transfer roller through an opening in the housing. At least one of the cleaning brush and the housing is biased to substantially the same electrical potential as the transfer roller.
