Process for controlling gloss in electrostatic images

摘要

A process for controlling gloss to fused toner images, comprising the steps of: A. passing an element bearing an unfused toner image through a fusing zone, a cooling zone and a release zone; and B. bringing the element bearing the unfused toner image into pressure contact with a fusing belt, thereby fusing the toner image to the element; characterized in that the fusing belt is a metal having (i) an unmatted powder coated tetrafluoroethylene/hexafluoropropylene (FEP) copolymer to provide a fused toner image having a coating gloss of 54-64; (ii) an unmatted powder coated polytetrafluoroethylene-co-perfluoropropyl vinylether copolymer (PFA) to provide a fused toner image having a coating gloss of 11-18 and (iii) an unmatted aqueous spray coated blend of polytetrafluoroethylene (PTFE) and polytetrafluoroethylene-perfluorinated vinyl ether (PFA) to provide a fused toner image having a coating gloss of 5-12.
