Abstract:
1. An image forming apparatus comprising: a heating rotatable member configured to heat a toner image on a recording material in a heating nip; a pressing rotatable member configured to form the heating nip by contact with said heating rotatable member; a first external heating member, contacting an outer peripheral surface of said heating rotatable member at a position that has passed through the heating nip, and configured to heat the outer peripheral surface of said heating rotatable member, wherein said first external heating member includes a parting layer at a surface where said first external heating member contacts the outer peripheral surface of said heating rotatable member; and a second external heating member configured to heat the outer peripheral surface of said heating rotatable member heated by said first external heating member, wherein said second external heating member includes a parting layer containing an electroconductive agent at a surface where said second external heating member contacts the outer peripheral surface of said heating rotatable member, wherein a contact angle of the parting layer of said first external heating member with respect to water is larger than that of the parting layer of said second external heating member, and a surface resistance of said second external heating member is lower than that of said first external heating member.
