Patent ID: 8879974

Claim:
An image heating device comprising: an endless belt including a base layer and an elastic layer formed around the base layer; a contact member contacting an inner surface of the endless belt; a pressure rotating member forming a nip portion configured to convey a recording material while nipping the recording material, along with the contact member via the endless belt; wherein an image formed on the recording material is heated at the nip portion using heat from the endless belt; wherein one end of the endless belt is coated with the elastic layer and the other end of the endless belt is not coated with the elastic layer; and a belt lateral shifting direction regulating mechanism configured to regulate a direction in which the endless belt shifts when the endless belt is rotated, toward the end coated with the elastic layer, wherein a pressure force applied between the contact member and the pressure rotating member is different between one end side and the other end side of the endless belt, and the different pressure force functions as the belt lateral shifting direction regulating mechanism.
