ABSTRACT:
Apparatus for removing residual electrostatic charge following image transfer from the surface of a photoconductive imaging layer such as selenium exhibiting substantially greater dark resistance to the flow of current in one direction than in the other. A resilient conductive cleaning member in wiping engagement with the imaging layer and supplied with slightly conductive cleaning liquid is supplied with a biasing potential relative to the imaging layer substrate of a polarity opposite to that of the residual charge. The biasing potential is of such a magnitude as to ensure that all portions of the imaging layer surface have discharged to the potential of the substrate within the period of contact.
