ABSTRACT:
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.
