Abstract
The image heating apparatus for heating an image formed on a recording medium has an endless belt with a base layer made of a metal material; a heater that contacts with an inner surface of the endless belt; and a backup member that forms a nip portion together with the heater through the endless belt. The image formed on the recording medium is heated while being pinched and conveyed in the nip portion. An end surface of the base layer includes a plane region and a curved surface region. When the thickness of the base layer is t, the width of the plane region in a thickness direction of the base layer is h, and the flatness ratio H of the end surface of the base layer is defined as h/t, the flatness ratio H satisfies 50%≦H≦90%.
