OFFSET TYPE ELECTROSTATIC IMAGE TREATMENT AND DEVELOPING AGENT

摘要

An offset electrostatic imaging process is disclosed which comprises the steps of (a) forming a latent electrostatic image on a dielectric imaging member (34), said dielecric imaging member being prepared by coating an electrically conductive substrate with a porous layer of a non-photoconductive metal oxide using a deposition process; (b) developing (38) the latent electrostatic image with a developer material which comprises a silicone polymer and from about 0.5 to about 5 percent by weight of a metal salt of a fatty acid; (c) transferring the developed image to an image receiving surface (22) by applying pressure (34, 36) between the dielectric imaging member (34) and the image receiving surface (22); (d) cleaning the dielectric imaging member using a first cleaning means (40) which is effective to remove developer material residue from above the surface of the porous oxide layer; and (e) further cleaning the dielectric imaging member using a second cleaning means (42) which is effective to remove developer material residue from the pores below the surface of the oxide layer.
