    摘要: An image forming apparatus includes a fixing unit for fixing a toner image on a recording sheet. In the fixing unit, a magnetic flux generator generates a magnetic flux to induce heat in a support roller. The heat is transferred to a fixing belt contacting the support roller. The recording sheet having the toner image is inserted between the fixing belt and a pressure roller facing the fixing belt. A holder holds the magnetic flux generator and positions the magnetic flux generator to face outer and inner circumferential surfaces of the support roller.

    摘要: An image forming apparatus includes a fixing unit for fixing a toner image on a recording sheet. The fixing unit includes a fixing belt, a support roller, and a coil. The fixing belt rotates and applies heat on the recording sheet to fix the toner image on the recording sheet. The support roller rotates and supports the fixing belt. The coil has a loop-like or U-like shape and generates a magnetic flux to induce heat in the fixing belt and the support roller. The coil sandwiches the support roller and the fixing belt in a manner that the coil faces an outer circumferential surface of the support roller via the fixing belt and an inner circumferential surface of the support roller. The above configuration of the coil controls a surface temperature of the fixing belt.

In at least one embodiment, the image fixing apparatus includes a magnetic flux generating member to generate a magnetic flux, and a heat member to generate heat with the magnetic flux. The heat member includes a first heat layer and a second heat layer having a relatively higher volume resistivity than the first heat layer, and having different thickness and/or different volume resistivity depending on a position in the width direction of the second heat layer. Portions of the magnetic flux generating member face different sides of the heat member.

    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.
