ABSTRACT:
The present invention provides an induction heating apparatus including a fixing belt that heats an unfixed image on recording paper, an excitation coil that induction-heats the fixing belt, an inverter circuit that supplies power to the excitation coil, a harness that electrically connects the excitation coil and the inverter circuit. The harness is constructed of a litz wire having a resistance of the harness section of 0.016 Ω or below formed by stranding several tens of wires which are conductive wires coated with an insulator into a predetermined thickness.
