Patent ID: 7643785

Claim:
An image heating device for heating an image formed on a recording material, comprising: a nip-forming member; a pressure-applying mechanism configured to apply pressure to the nip-forming member so as to form a heating nip where the recording material is heated; a pressure-changing mechanism including a rotatable cam member acting on the pressure-applying mechanism so as to change the pressure applied to the nip-forming member by the pressure-applying mechanism; and a one-way clutch mechanism, wherein the cam member is attached to a rotating shaft of a rotating body that can be brought into contact with the recording material via the one-way clutch mechanism, and wherein the cam member is not rotated when the rotating body is rotated in a direction in which the recording material is conveyed, and the cam member is rotated when the rotating body is rotated in a direction opposite to the conveying direction of the recording material.
