Abstract
An apparatus which cleans a photoconductive surface having residual charged particles of opposite polarities thereon. Oppositely electrically biased cleaning brushes remove particles from the photoconductive surface with each brush being located in the chamber of a different housing with each housing electrically biased to the same magnitude and polarity as the brush located within the housing. The particles are then attracted from the cleaning brushes to electrically biased detoning rolls.
