Abstract
An image heating apparatus includes a first heat generating element; a second heat generating element which is arranged adjacent to the first heat generating element in a longitudinal direction; and a control portion which controls power supplied to the first and second heat generating elements. When an image exists in a second region on the recording material heated by the second heat generating element but an image does not exist in a first region on the recording material heated by the first heat generating element, the control portion sets a control temperature of the second heat generating element when heating the second region, in accordance with a distance between an end section of the image in the second region and a boundary of the first region and the second region.
