Patent ID: 8849169

Claim:
An induction heating-type fixing device, comprising: a fixing member including a heat generating layer to heat and fuse a toner image on a recording medium; an excitation coil wound a predetermined number of times and facing an outer surface of the fixing member, to generate a magnetic flux relative to the fixing member; a magnetic core to form a continuous magnetic path to direct the magnetic flux generated by the excitation coil to the fixing member, the magnetic core including a plurality of side cores disposed at sides of the excitation coil and facing the fixing member; a holder to hold the excitation coil and the magnetic core, the plurality of side cores is exposed from the holder, the holder includes a plurality of notches and a plurality of reinforcing members to reinforce the holder, and the plurality of reinforcing members is disposed between the plurality of side cores; and a pressing member disposed opposite the fixing member to press against the fixing member and form a fixing nip between the fixing member and the pressing member through which the recording medium is conveyed, the magnetic core exposed from the holder at a fixing member side.
