ABSTRACT:
A heat fixing member according to the invention has a surface layer formed on the surface of the substrate with a three-layer structure of a primer layer, an middle layer, and a topcoat layer. The binder-resin content decreases in order from the primer layer to the topcoat layer. The fluorocarbon-resin content increases in order from the primer layer to the topcoat layer. The topcoat layer is made of a fluorocarbon resin having high ability of release and a fluorocarbon resin having high abrasion resistance. Thus, the surface layer can be prevented from peeling without losing ability of release and can be decreased in abrasion.
