An image heating apparatus has a flexible rotatable member; a slidable member
for sliding contact with an inner surface of the rotatable member; a back-up member
for forming a nip with the slidable member with the rotatable member interposed
therebetween, wherein a projection extended along a longitudinal direction of the
rotatable member, and provided on such a portion of a sliding surface of the slidable
member as is downstream of a center of the sliding surface with respect to a recording
material feeding direction in which the recording material is fed, and wherein
the projection is effective to provide a maximum pressure in a distribution, with
respect to the recording material feeding direction, of pressure applied to the nip.
