Patent ID: 8355035

Claim:
An apparatus for imparting an image onto a substrate, comprising: a photoreceptive member whose conductivity may be selectively locally changed by the incidence of light thereon; an electrically insulative spacer layer formed over said photoreceptive member, said spacer layer comprising a plurality of lands which define a plurality of physically and electrically isolated cells over said photoreceptive member; a surface application material application mechanism for applying a liquid surface application material over the spacer layer and thereby at least partially fill said cells; a charging mechanism for applying a charge to liquid surface application material within said cells; an optical addressing system for individually optically addressing each said cell, said optical addressing system initiating the transfer of charge on said liquid surface application material within any cell which said optical addressing system exposes to light; and a transfer mechanism for selectively substantially transferring either charged or uncharged liquid surface application material from said cells to an image receiving member while substantially not transferring the remainder of the liquid surface application material from said cells to said image receiving member.
