The non-sheet-feeding portion temperature rise is reduced during warm-up operation of an image heating apparatus, the time needed for the warm-up operation is reduced, and the accuracy of the image fixing operation is improved. When a CPU determines that a temperature detected by an end portion thermistor is higher than a temperature detected by a center portion thermistor, the CPU controls the temperature of a fixing heater based on a detection result of the end portion thermistor. When the CPU determines that the temperature detected by the end portion thermistor is equal to or less than the temperature detected by the center portion thermistor, the CPU controls the temperature of the fixing heater based on a detection result of the center portion thermistor.
