Abstract
An image heating device heats up an image formed on a recording material, the device having: a heating member provided with a heater having a plurality of heating elements juxtaposed in a direction perpendicular to a conveyance direction of the recording material; a roller, such that the circumference of the roller increases from a central portion towards ends portions, in a direction perpendicular to the conveyance direction; and a control portion that controls individually the power supplied to the plurality of heating elements. The control portion sets a control target temperature, being set in order to supply power to a heating element corresponding to a non-sheet passing area, from among the plurality of heating elements, to be higher than a lowest control target temperature from among control target temperatures that are set in order to supply power to a heating element corresponding to a sheet passing area.
