Abstract:
1. A fixing device comprising: a fixing member that includes a conductive layer and that fixes toner onto a recording medium with the conductive layer self-heated by electromagnetic induction; a drive unit that rotationally drives the fixing member; a magnetic field generating member that generates an alternate-current magnetic field intersecting with the conductive layer of the fixing member; a magnetic path forming member that is arranged so as to be in contact with an inner peripheral surface of the fixing member, that forms a magnetic path of the alternate-current magnetic field generated by the magnetic field generating member, and that transmits heat to the fixing member by being self-heated by electromagnetic induction; an induction member that is arranged so as to be in contact with an inner peripheral surface of the magnetic path forming member, that induces magnetic field lines having passed through the magnetic path forming member and that diffuses heat generated at the magnetic path forming member; and an elastic member that has force in a direction to press the magnetic path forming member and the induction member against the inner peripheral surface of the fixing member.
