An image heating apparatus configured to heat an image formed on a recording material, the image heating apparatus comprising: a heater, the heater having a plurality of heat generating elements (HB1 to HB7) arranged in a direction orthogonal to a conveying direction of the recording material; and a control portion configured to control 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 is configured to respectively set 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, characterized in that the control portion is further configured to at least set the heating amount with respect to the region in which the image is not formed when the recording material is heavy paper to become smaller than the heating amount with respect to the region in which the image is not formed when the recording material is plain paper so that a difference between the heating amount with respect to the region in which the image is formed and the heating amount with respect to the region in which the image is not formed when the recording material is heavy paper becomes larger than a difference between the heating amount with respect to the region in which the image is formed and the heating amount with respect to the region in which the image is not formed when the recording material is plain paper, and that the control portion is further configured to set 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, so that the smaller a basis weight of the recording material, the smaller the difference in heating amounts. a heater, the heater having a plurality of heat generating elements (HB1 to HB7) arranged in a direction orthogonal to a conveying direction of the recording material; and a control portion configured to control 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 is configured to respectively set 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, characterized in that the control portion is further configured to at least set the heating amount with respect to the region in which the image is not formed when the recording material is heavy paper to become smaller than the heating amount with respect to the region in which the image is not formed when the recording material is plain paper so that a difference between the heating amount with respect to the region in which the image is formed and the heating amount with respect to the region in which the image is not formed when the recording material is heavy paper becomes larger than a difference between the heating amount with respect to the region in which the image is formed and the heating amount with respect to the region in which the image is not formed when the recording material is plain paper, and that the control portion is further configured to set 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, so that the smaller a basis weight of the recording material, the smaller the difference in heating amounts.
