ABSTRACT:
The fixing device includes: a fixing member including a conductive layer and fixing toner onto a recording medium with the conductive layer self-heated by electromagnetic induction; a drive unit rotationally driving the fixing member; a magnetic field generating member generating an alternate-current magnetic field intersecting with the conductive layer; a magnetic path forming member being in contact with an inner peripheral surface of the fixing member, forming a magnetic path of the alternate-current magnetic field, and transmitting heat to the fixing member by being self-heated by electromagnetic induction; an induction member that is in contact with an inner peripheral surface of the magnetic path forming member, that induces magnetic field lines and that diffuses heat; and an elastic member having force in a direction to press the magnetic path forming member and the induction member against the inner peripheral surface of the fixing member.
