MAGNETIC INDUCTION EXOTHERMIC ROLLER AND METHOD OF PRODUCING THE SAME, AND HEATING DEVICE AND IMAGE FORMING DEVICE

摘要

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
