Abstract
The image heating apparatus heats a toner image beard on a recording material while conveying the recording material at a nip portion, and includes: a heater; a fixing member; a pressure member; a first temperature detecting member; a second temperature detecting member configured to detect a temperature on non-sheet-passing area; a control device; and an air supplying member supplying an air to the non-sheet-passing area. The air supplying member is started to be drive when a temperature detected by the second temperature detecting member reaches a predetermined temperature which is higher than the target temperature. The control device controls the quantity of the air in response to information related to the power supplied to the heater when a temperature detected by the second temperature detecting member reaches the predetermined temperature.
