An image heating device includes a conveyance belt having a heat generation layer, and a first electrode portion, a second electrode portion and a third electrode portion that are in contact with the heat generation layer. The conveyance belt conveys a recording medium that includes an image. A first heat generation region formed on the conveyance belt between the first electrode portion and the second electrode portion generates heat to a first temperature that is equal to or greater than a deformation temperature at which a material forming the image is deformable. A second heat generation region formed between the second electrode portion and the third electrode portion generates heat to a second temperature that is different from the first temperature. The first heat generation region and the second heat generation region are located in a region of the conveyance belt to contact the recording medium.
