A fixation device which comprises a roller comprising a core member, a fluororesin-containing rubber layer on the core member and a fluororesin surface layer. The fluororesin surface layer has a thickness from 2 to 100 .mu.m, preferably 5 to 30 .mu.m, and surrounds and contacts the outside of the rubber layer.

DETAILED DESCRIPTION It is an object of the present invention to provide a roller fixation device which uses a roller having fluororesin surface layer as a heat roller or a pressure roller excellent in durability as well as in mold releasability.
The present invention has been made to accomplish the above object.
The above object of this invention is accomplished by a fixation device comprising a revolving body to serve as a heat roller or a pressure roller having thereon a fluororesin-containing elastic layer such as a rubber layer, or a layer having a rubber-like elasticity, on the exterior of which is a surface layer formed by coating thereon with a fluororesin, or by a fixation device comprising a revolving body as a heat roller or a pressure roller having thereon a fluororesin-containing rubber layer, on which is formed a fluororesin layer preferably 5 to 30 .
