A manufacturing method for an image heating apparatus for heating an image
on a recording material by a heat from a heat generating element for
producing heat by a magnetic flux generated by magnetic flux generating
means, the apparatus including a magnetic flux confining member for
confining a magnetic flux directing toward a predetermined region of the
heat generating element from the magnetic flux generating means, and a
first drive transmission member, provided at one end of the magnetic flux
confining member, for transmitting rotational drive to the magnetic flux
confining member and a second drive transmission member, provided at the
other end of the magnetic flux confining member, for transmitting
rotational drive to the magnetic flux confining member, the method
comprising an adjusting step of adjusting such that first and second
drive transmission members are supported by the magnetic flux confining
member with a predetermined rotational position relation, using marks
provided on the first and second drive transmission members,
respectively.
