PURPOSE:To enable an oil impregnated into a fixing-roller to be effectively used and lengthened in life by forming the outermost layer of a pressing roller made by calcining a mixture essentially composed of a fluororubber and a fluororesin. CONSTITUTION:The pressing roller 5 is manufactured by coating a core metal 6 made of metal or the like with a primer layer, covering the primer layer with a heat-resistant elastic material layer 7 formed by adding a wet filler to a heat-resistant silicone rubber, and forming the outermost layer 8 prepared by calcining a mixture essentially composed of a fluororubber and a fluororesin on the outer circumference of the layer 7 by interposing a primer layer. |
