A fixing device comprises a heat roller (201) constructed from a material which generates heat by eddy currents, an induction heating element (207; 270) which causes the heat roller to generate the eddy currents by electromagnetic induction, and a pressing roller (202) for pressing a ink material-applied recording medium (2) against the heat roller. The induction heating element comprises an arc-section insulating support (208; 272) placed adjacent to the surface of the heat roller, and a conductive line (209;271) through which flows a drive current which causes electromagnetic induction resulting in the passage of the eddy currents. The heat roller is excited by the magnetic flux provided by the passage of the drive current through the conductive line of the induction heating element, thereby generating eddy currents. The eddy currents cause Joule heat which heats the heat roller. <IMAGE> |
