Abstract
An induction heating-type fixing device includes a fixing member, an excitation coil, a magnetic core, a holder, and a pressing member. The fixing member includes a heat generating layer to heat and fuse a toner image on a recording medium. The excitation coil wound a predetermined number of times is disposed facing an outer surface of the fixing member, to generate a magnetic flux relative to the fixing member. The magnetic core forms a continuous magnetic path to direct the magnetic flux generated by the excitation coil to the fixing member. The holder holds the excitation coil and the magnetic core. The pressing member is 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 is exposed from the holder at the fixing member side.
