Abstract
In a case where an image formed on a recording material includes a contiguous image portion formed across a plurality of heating regions at a given density, power supplied to a plurality of heating elements that heat the plurality of heating regions is controlled by correcting respective control heating amounts of the plurality of heating regions set in accordance with respective maximum densities of image regions resulting from dividing the image into the plurality of heating regions, so that a difference between a maximum value and a minimum value of the control heating amounts among the plurality of heating regions in which the image portion is heated from among the plurality of heating regions, lies within a predetermined range.
