Abstract
A fixing roller is configured in a manner that a conductive primer layer, a conductive intermediate layer, and a non-conductive outermost layer (a release layer) are coated sequentially onto a surface of an outer circumference of a hollow cylindrical cored bar. The intermediate layer is composed of a non-conductive fluorine resin layer having conductive materials dispersed therein, and a surface thereof is a rough surface having a large number of convex portions and concave portions formed thereon. The outermost layer is composed of a non-conductive fluorine resin only, and a surface thereof is a flat and smooth surface so as to ensure a favorable release property of a recording medium.
