Abstract
Abstract The present invention provides a roller fixation device which uses a roller having fluororesin surface layer as a heat roller or a pressure roll of excellent durability as well as mold releasability. The fixation device may comprise a revolving body to serve as a heat roller or a pressure roller having thereon a fluororesin-mixed elastic layer such as a rubber layer, or a layer having a rubber-like elasticity, on the outside of which is a surface layer formed by coating thereon with fluororesin-coated surface layer, or 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 2-to-100µm-thick fluororesin layer.
