Zusammenfassung:In this image heating device, a control portion controls the supply of electric power to a plurality of heating elements such that a first average temperature which is an average value of control target temperatures of heating regions included in a first region located closer to one end side than a central heating region in a direction orthogonal to a conveying direction of a recording material among a plurality of heating regions heated by a plurality of heating elements of a heater and a second average temperature which is an average value of control target temperatures of heating regions included in a second region located closer to the other end side than the central heating region are within a predetermined temperature range.
