Abstract
The present invention is characterized in that a control portion respectively sets a heating amount with respect to a region in which an image is formed and a heating amount with respect to a region in which an image is not formed in a single sheet of a recording material, and a difference between the heating amount with respect to the region in which an image is formed and the heating amount with respect to the region in which an image is not formed differs depending on a type of the recording material.
Claims20
An image heating apparatus that heats an image formed on a recording material, the image heating apparatus comprising:
- a heater, the heater having a plurality of heat generating elements arranged in a direction orthogonal to a conveying direction of the recording material;
- and
- a control portion that controls electric power to be supplied to the plurality of heat generating elements, the control portion being capable of individually controlling the plurality of heat generating elements, wherein the control portion respectively sets a heating amount with respect to a region in which an image is formed and a heating amount with respect to a region in which an image is not formed in a single sheet of the recording material, and
- a difference between the heating amount with respect to the region in which an image is formed and the heating amount with respect to the region in which an image is not formed differs depending on a type of the recording material.
