ABSTRACT:
The image heating apparatus for heating a toner image formed on a recording material, includes a rotatable member, a pressure roller which contacts with the rotatable member, wherein the recording material is heated while being conveyed by a nip portion between the rotatable member and the pressure roller, a charge eliminating member for eliminating a charge on a surface of said pressure roller, the charge eliminating member being grounded, wherein the pressure roller includes an electrically insulating elastic layer and an electrically insulating releasing layer. Thus the image heating apparatus can suppress a toner offsetting even in a high-speed heating process.
