摘要： A fixing device (200) using a heating device of an electromagnetic induction heating system, comprising an exciting device (230) generating magnetic fluxes, an opposed core (233) disposed oppositely to the exciting device (230), a fixing belt (210) induction-heated by the magnetic fluxes, and a magnetic shielding body (301) shielding a magnetic path (302) corresponding to the paper non-passage area of the fixing belt (210) between the exciting device (230) and the opposed core (233). Since the magnetic path passed between the exciting device (230) and the opposed core (233) is shielded by the magnetic shielding body (301), the overheat of the paper non-passage area of the fixing belt (210) can be prevented by effectively shielding the magnetic fluxes induction-heating the fixing belt (210).
