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.
