ABSTRACT:
In the device and method of the present invention, a stripping roller is positioned a short distance from an electrostatically charged photoconductor surface in an electrophotocopy machine. The roller is supplied with a bias voltage which has a polarity the same as that of the charge on the photoconductor surface and a magnitude which is equal to or higher than that of the photoconductor surface charge, but greater than 1 kV. The photoconductor surface is moved past the stripping roller to remove excess developer liquid.
