Abstract
A heating roller 10 comprises a surface layer 157 formed of a prepreg material including carbon fibers having a high tensile strength and a high elastic modulus, and a heating unit 153 mounted in the inner area of the surface layer and communicated to a power supply unit 30 formed of a prepreg material including carbon fibers having a high electric resistance. A metal material working as an electrode 20 communicated to the power supply unit 30 and the heating unit 153 is mounted to both ends of the heating roller 10. The electric resistance of the heating unit 153 is adjusted either by changing the thickness (number of laminated layers) of the prepreg material including carbon fibers, or by adjusting the mounting angle of the carbon fibers inside a prepreg material being laminated and the angle of the carbon fibers inside another prepreg material being laminated. Moreover, the carbon fibers of the heating unit 153 are uniformly mounted in the circumferential direction of the roller, so as to obtain a uniform surface temperature.
