Abstract
Toner removal device for removing residual toner and debris from a charge retentive surface after transfer of toner images from the surface. This device is characterized by the use of a pair of detoning rolls, one for removing toner from a biased cleaner brush and the other for removing debris such as paper fibers and Kaolin from the brush. The rolls are electrically biased so that one of them attracts toner from the brush while the other one attracts debris. Thus, the toner can be reused without degradation of copy quality while the debris can be discarded.
