Abstract
The image fixing apparatus includes a heater having a heat generating resistor on a substrate, a heater holder for holding said heater, and a backup roller for forming a nip portion in cooperation with said heater, wherein said heater holder has, in a direction along a short side of said heater, a contact area facing said resistor forming area and coming into contact with said heater, and non-contact areas provided on both sides of the contact area and not coming into contact with said heater, and the contact area has a width equal to or larger than the resistor forming area. With this configuration, it is possible to provide the image fixing apparatus capable of restraining a stress applied to the heater and an image heating apparatus capable of restraining a rise in temperature of a sheet non-feeding portion.
