    Abstract: A heating roller (21) has a heating layer (22) for electromagnetic induction heating, a heat insulating layer (23), and a support layer (24) from inside to outside in this order. The support layer (24) consists of a material with a specific resistance of 1 x 10 −5 Ωm or more. Thus, despite of thinning down the heating layer (22) below the skin depth that is a thickness for an induction current to flow to make a magnetic flux penetrate through the heating layer (22) and reach the support layer (24), the support layer (24) is blocked from heating by an eddy current. Therefore, reductions in the heat capacity of the heating layer (22) and the heating of the support layer (24) are suppressed. The efficient heating of only the heating layer (22) enables a shortening in warm−up time and prevents a bearing or the like for supporting the heating roller (21) from being damaged by heat.

    Abstract: An electromagnetic induction exothermic roller (21) having, in the order from the surface, at least a release layer, induction exothermic layer (22), an elastic layer (23), and a core (24). Exothermic roller (21) is pressed by a press member (31) to form a nip portion (34) and heat up a heating subject material (11) passing through the nip portion (34). The induction exothermic layer (22) has a layer prepared by dispersing an electrically conductive filler in the base material consisting of a heat resistant resin or heat resistant rubber. For this reason, the induction exothermic layer (22) can easily deform, so that a nip portion (34) having a large width (W) can be formed. Further, the durability of the induction exothermic layer (22) against repeated bending is improved.
