ABSTRACT:
A transfer cleaning station for an electrostatic marking system is provided. In this station, the upper surface of a movable transfer belt is cleaned by a rotating electrostatic cleaning brush (ESB). To improve cleaning performance and conserve space, a grounded conductive brush is placed below an inside surface of the belt so that an electrostatic cleaning field is created between it and the ESB. The grounded conductive brush is located in a previously unused space between two upper rollers in the station.
