Abstract
Abstract An imaging system comprising an imaging member including a deformable metallic layer arranged between a pair of deformable layers, at least one of which comprises an elastomer material. In operation an electrical field is established across the deformable layers to cause deformation thereof in imagewise configuration. The imaging member may include photoconductive material and may include a pair of electrodes for establishing an electrical field across the deformable layers. In one embodiment the electrodes may comprise an electrical X-Y matrix address system.
