Intermediate transfer surface and method of color printing

A method of xeroprinting a color image onto a receiving substrate comprising the steps of:

• (a) forming a conductive intermediate transfer surface having conductive fibers or particles each less than about 5 microns in size dispersed therein;
• (b) imaging an electrostatically imagable surface to create a master with a latent image thereon;
• (c) developing the latent image with a liquid color toner;
• (d) electrostatically transferring the developed image across a liquid-filled gap to the conductive intermediate transfer surface, the conductive intermediate transfer surface further being a conductive fluorocarbon selected from the group consisting of a copolymer of tetrafluoroethylene and propylene;
• a copolymer of hexafluoropropylene and vinylidene fluoride;
• a dipolymer of hexafluoropropylene and vinylidene fluoride;
• terpolymers of hexafluoropropylene, vinylidene fluoride and tetrafluoroethylene;
• and polytetrafluoroethylene;
• (e) heating the conductive intermediate transfer surface;
• and
• (f) transferring the developed image to a receiving surface by contact transfer.
