Abstract
Apparatus and method for transferring non-fused xerographic toner images from a first support material, such as a photoconductive insulating surface, to a second support material, such as paper, and fusing the toner images to the second support material. Such apparatus includes an intermediate transfer member having a smooth surface of low surface free energy and a hardness of from 3 to 70 durometers. The intermediate transfer member can be, for example, a 0.1-10 mil layer of silicone rubber coated onto a polyimide support. The member can be formed into belt or drum configuration.
