<p>A pressure roller for use in a fixing device includes a core metal, an elastic layer, and a releasing layer. The releasing layer is made of at least one fluorine resin selected from among tetrafluoroethylene-perfluoroalkyl vinyl ether copolymer, ethylene-tetrafluoroethylene copolymer, and tetrafluoroethylene-hexafluoropropylene copolymer. The fluorine resin contains at least one polymer selected from among polyvinylidene fluoride, polyacrylonitrile, and polymethyl methacrylate, and monomer electrolyte.</p> |
