Abstract:
An image heating apparatus includes a cylindrical film, a heater, a roller forming a nip with the film, a first temperature sensor in a first area of the film passed by a minimum width sheet that is capable of being fed by the apparatus, a second temperature sensor in a second area of the heater which is outside an area to be passed by a minimum width sheet and which is passed by a maximum width sheet, a third temperature sensor in a third area of the heater outside the second area, and a controller. When a large width sheet is heated, the controller executes a first heater control responsive to the temperatures detected by the first temperature sensor and by the second temperature sensor. When a small width sheet is heated, the controller executes a second heater responsive to the temperature detected by the first temperature sensor only.

Claim (Index 1):
An image heating apparatus for heating an image on a recording material, said image heating apparatus comprising:\n a cylindrical film; a heater contacting an inner surface of said film; a roller cooperative with said heater to form a nip with said film; a first temperature detecting element configured to detect a temperature of said film in a first area of said film which is passed by a minimum width recording material that is capable of being fed by said apparatus; a second temperature detecting element configured to detect a temperature of said heater in a second area of said heater which is outside of a area to be passed by a minimum width recording material that is capable of being fed by said apparatus and which is passed by a maximum width recording material that is capable of being fed by said apparatus; a third temperature detecting element configured to detect a temperature in a third area of said heater which is outside of the second area with respect to an longitudinal direction of said heater; and a controller configured to control said heater, wherein said device heats the recording material carrying the image while passing through the nip, wherein when the recording material having a width enough to pass both the first area of said film and the second area of said heater is heated, said controller executes a first heater control for controlling said heater on the basis of both of the temperature detected by said first temperature detecting element and the temperature detected by said second temperature detecting element, and wherein when the recording material having a width to pass the first area of said film and not to pass the second area of said heater is heated, said controller executes a second heater control for controlling said heater on the basis of the temperature detected by said first temperature detecting element irrespective of the temperature detected by said second temperature detecting element.
