ABSTRACT:
An image heating device has a magnetic flux generator, a heat generating element for generating heat by a magnetic flux from the magnetic flux generator; a magnetic flux confining member, the magnetic flux confining member including a magnetic flux confining portion for confining the magnetic flux directed toward a predetermined region of the heat generating element at a predetermined magnetic flux confining position and a connecting portion connecting with the magnetic flux confining portion in a longitudinal direction of the heat generating element to hold the magnetic flux confining portion; and a moving unit for moving the magnetic flux confining member to a magnetic flux confining position or to a retracted position where the magnetic flux confining member is retracted from the magnetic flux confining position, wherein the connecting portion has a regulating member for preventing movement to the magnetic flux confining position.
