Patent ID: 8270887

Claim:
A fixing device, comprising: a fixing member comprising a conductive layer configured to heat by electromagnetic induction; a magnetic field generating member that generates an alternate-current magnetic field intersecting with the conductive layer of the fixing member; a plurality of magnetic path forming members that form a magnetic path of the alternate-current magnetic field generated by the magnetic field generating member; a support member that supports the magnetic field generating member; an elastic support member that is arranged between the magnetic field generating member and the plurality of magnetic path forming members to be in contact with the plurality of magnetic path forming members; a pressing member that presses the plurality of magnetic path forming members toward the magnetic field generating member; a second support member that supports the plurality of magnetic path forming members such that the plurality of magnetic path forming members are movable in a width direction of the fixing member; and a position setting member that sets and secures each of the magnetic path forming members at a position set in advance in the width direction of the fixing member, each of the magnetic path forming members being movably supported by the second support member.
