Patent ID: 8000623

Claim:
A fixing apparatus comprising: a heating member having an outer peripheral surface which is heated; a first temperature detecting member, located in parallel with a heating member extending direction in which the heating member extends and at a predetermined angle with a direction of radiation of the heating member, in a substantially central portion in the heating member extending direction and not in contact with the heating member, wherein the first temperature detecting member includes a detection surface which is inclined at a predetermined angle to the outer peripheral surface of the heating member; a second temperature detecting member, located in parallel with the heating member extending direction and at the predetermined angle with the direction of radiation of the heating member, in one of first and second ends of the heating member extending direction and not in contact with the heating member, wherein the second temperature detecting member includes a detection surface which is inclined at a predetermined angle to the outer peripheral surface of the heating member; and a heating device which heats the heating member to a target temperature on the basis of the temperatures detected by the first and second temperature detecting members.
