Abstract

A pair of spaced, insulating rolls resiliently press an intermediate insulating belt having transverse conductive strips against a photoconductive surface over a transfer zone. Contact brushes connect the conductive strips to voltage sources to individually tailor the mechanical and electrical forces to achieve high quality transfer of a liquid image. The belt may be made from a porous foam having insulatin and conducting sections. The insulating rolls may also
