Abstract: A fixing roller of an image forming apparatus is provided not to generate a harmful material in performing a printing operation by including a glass fiber insulating layer which is incombustible, smokeless, and non-gaseous. A coated layer(11) serves to improve releasing properties of a sheet toner image that passes between a fixing roller(10) and a pressing roller(20), and mainly made of teflon. A conductive pipe(12) has conductor properties to allow certain current therethrough and made of an aluminum material. A heating coil(14) uses resistance heating by an electric resistance or may use induced heating according to an induction current by applying AC to a coil. An outer insulating layer(13) and an inner insulating layer(15) do not cause a dielectric breakdown by the AC inputted to the heating coil, and insulate the heating coil so that a leakage current cannot flow to the conductive pipe or a core pipe(16).
