Image fixing apparatus and an image formation apparatus including a magnetic flux adjuster
Abstract:
An image fixing apparatus includes a fixing member, a magnetic flux generator, a heat member, a core, and a magnetic flux adjuster. The fixing member fixes the toner image onto the recording medium. The magnetic flux generator generates a magnetic flux. The heat member has a heat layer which is heated inductively by the magnetic flux generated by the magnetic flux generator and heats the fixing member. The core faces the magnetic flux via the heat member. The magnetic flux adjuster is configured to vary a heating range of the heat member in the width direction. The heat layer has a predetermined Curie point.
