PROBLEM TO BE SOLVED: To make it possible, in an image heating device 115 that has a high heat conduction member 220 between a heating body 300 and a support member 201 of the heating body, to easily check if the high heat conduction member is accurately disposed.SOLUTION: A support member 201 has, on both sides in the width direction of a heating body 300, a heating body support part 201-1 that regulates a longitudinal side face 300a of the heating body along the longitudinal direction of the heating body and a heating body non-supporting part 201-2 that does not regulate the longitudinal side face 300a. When the width of an opening between the heating body non-supporting part 201-2 on one side and the heating body non-supporting part 201-2 on the other side, which face to each other, is 201Wa, the width of a portion of a high heat conduction member 220 corresponding to the opening is 220Wa, and the width of the heating body 300 is 300W, width 201 Wa≥width 220 Wa>width 300 W. |
