ABSTRACT:
An image heating device includes a movable belt for heating an image on a recording material; a supporting member, having an elastic layer, for supporting the belt, the supporting member having an outer diameter which is larger in a central portion than at opposite end portions; a pressing rotatable member, pressed toward the supporting member with the belt interposed therebetween, for forming the nip for nipping and feeding the recording material; and pressing means for supporting opposite end portions of the supporting member and for pressing the supporting member and the pressing rotatable member toward each other; wherein a surface hardness of the supporting member through the belt is smaller than a surface hardness of the pressing rotatable member, and the pressing roller has a straight configuration in a longitudinal cross-section.
