Abstract
An electrophotographic fuser roll includes a hard external surface having low surface energy and high abrasion resistance. This surface is formed by sequentially coating a metal roll with two layers of a polymeric material. The polymeric material is not cured until after the second layer is applied. Once the material is cured, it is subjected to a polishing step that also generates heats. In this way, the roll's surface is both polished and heat treated.
