    摘要: 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.

    摘要: A fixing device includes a pressurization member pressed against a fixing rotator and a magnetic flux generator disposed opposite the fixing rotator. A heat generator is disposed opposite the magnetic flux generator to generate heat by a magnetic flux generated by the magnetic flux generator. A magnetic shield is movably disposed inside the heat generator to screen the magnetic flux penetrating through the heat generator. A pressure adjuster presses the pressurization member against the fixing rotator with variable pressure. An interlock interlocks the pressurization member with the magnetic shield. The pressure adjuster presses the pressurization member against the fixing rotator with increased pressure to move the magnetic shield via the interlock to a proximate position in proximity to the heat generator and with decreased pressure to move the magnetic shield via the interlock to a remote position being remote from the heat generator.
