摘要： A fixing device includes an endless belt rotatable in a predetermined direction of rotation and a nip formation assembly disposed opposite an inner circumferential surface of the endless belt. An opposed rotary body is pressed against the nip formation assembly via the endless belt to form a fixing nip between the endless belt and the opposed rotary body through which a recording medium bearing a toner image is conveyed. A belt holder contacts and supports each lateral end of the endless belt in an axial direction thereof. The belt holder is isolated from the opposed rotary body with a first interval interposed therebetween in the axial direction of the endless belt.

摘要： A separator includes a front edge disposed opposite an outer circumferential surface of an endless belt. The front edge contacts and separates a recording medium from the endless belt. A separation plate mounts the front edge. A contact plate projects from the separation plate in an axial direction of the endless belt and contacts a belt holder that supports the endless belt. A bracket projects from the separation plate in a direction orthogonal to the direction in which the contact plate projects from the separation plate. The bracket includes a notch that engages the belt holder. The contact plate contacting the belt holder and the notch of the bracket engaging the belt holder produce an interval between the front edge of the separator and the outer circumferential surface of the endless belt.

The endless flexible belt is looped into a generally cylindrical configuration extending in an axial direction thereof for rotation in a rotational, circumferential direction thereof. The stationary pad is stationarily disposed inside the loop of the belt. The rotary pressure member is disposed parallel to the belt. The rotary pressure member presses against the stationary pad via the belt to form a nip therebetween. The reinforcing member is stationarily disposed in contact with the stationary pad inside the loop of the belt for reinforcing the stationary pad. The stationary pad includes two or more contact portions spaced apart from each other in the conveyance direction, each generally extending in the axial direction of the looped belt and protruding toward the reinforcing member to contact the reinforcing member.

摘要： An image forming apparatus includes an image forming mechanism and an image fixing unit. The image forming mechanism forms a toner image on a recording sheet. The image fixing unit fixes the toner image onto the recording sheet. The image fixing unit includes a magnetic flux generator, a heat member, a magnetic flux adjuster, and a controlling member. The magnetic flux generator generates a magnetic flux. The heat member is heated inductively by the magnetic flux generated by the magnetic flux generator. The magnetic flux adjuster reduces the magnetic flux active on the heat member to form a heat reduction area in an outer circumferential surface of the heat member in a width direction thereof. The controlling member moves the magnetic flux adjuster to change the heat reduction area.
