Image forming apparatus

An image heating device comprising:

• a magnetic flux generating unit which generates magnetic flux;
• a heat generating member which generates heat by the magnetic flux to heat a image on a recording material;
• a magnetic flux confining unit which confines the magnetic flux directed toward said heat generating member from said magnetic flux generating unit, said magnetic flux confining unit including a magnetic flux confining portion for confining the magnetic flux directed toward a predetermined region of said heat generating member at a predetermined magnetic flux confining position;
• a moving unit which moves said magnetic flux confining portion to a magnetic flux confining position and to a retracted position where said magnetic flux confining portion is retracted from said magnetic flux confining position;
• a position detecting member for detecting a position of said magnetic flux confining portion;
• a stop unit which stops said magnetic flux confining portion at a predetermined stopping position on the basis of an output of said position detecting member;
• a movable member movable in interrelation with movement of said magnetic flux confining portion;
• and
• a regulating unit which regulates movement of said magnetic flux confining portion by contacting to said movable member,
• wherein said stop unit stops the movement of said magnetic flux confining portion in a region where said movable member is not contacted with said regulating unit, and said regulating unit stops the movement of said magnetic flux confining portion when said movable member is contact to said regulating unit.
