ABSTRACT:
Cleaning apparatus for removing residual toner particles from a charge retentive surface. The apparatus utilizes a cleaning brush to which an electrical bias is applied in order to enhance the toner removal. The brush has different biases applied thereto in accordance with the area of the charge retentive surface being cleaned. Thus, when toner is being removed from the document area of the charge retentive surface, one bias level is applied and when the interdocument area is being cleaned a different bias is applied thereby increasing the cleaning latitude.
