Claim Text:
1. A fixing device thermally fixing an unfixed image onto a sheet through heat of a heating body that is heated through electromagnetic induction, the fixing device comprising: an excitation coil generating flux for heating the heating body; one or more core members disposed opposite the heating body with respect to the excitation coil; a thermo-electric conversion element disposed farther from the excitation coil than the core members; and a thermally conductive member connected to the excitation coil and to a heat-absorbing face of the thermo-electric conversion element, transferring heat from the excitation coil to the thermo-electric conversion element, wherein the core members are disposed in a row with separation from each other, the thermally conductive member is a bobbin around which the excitation coil is wound, the bobbin is provided with an extension extending toward a space between a neighbouring pair of the core members, the extension has a tip passing through the space so as to be arranged farther from the excitation coil than the core members, and the thermo-electric conversion element is affixed to a portion of the tip of the extension.
