Abstract:
1. A fixing apparatus comprising: a magnetic flux generation section that generates magnetic flux; a heat-producing element of a nonmagnetic electrical conductor, that allows passage of the magnetic flux and is induction-heated; at least one magnetism masking element that masks the magnetic flux; and a magnetic flux adjustment section that switches between masking and clearing of magnetic flux with respect to a paper non-passage area of said heat-producing element, wherein said magnetism masking element is located on the opposite side of said magnetic flux generation section across the heat-producing element, and, when said heat-producing element produces heat, said magnetism masking element is positioned, by said magnetic flux adjustment section, at a position where the magnetic flux is masked with respect to a paper non-passage area of said heat-producing element and suppresses heat in the paper non-passage area.
