    摘要: An image heating apparatus for heating an image formed on a recording material, the apparatus including a conveying roller for conveying a recording material, the conveying roller including a metal core and an elastic layer provided outside the metal core, wherein the metal core has, in a central portion in the longitudinal direction thereof, a straight shape area having a substantially uniform diameter along the longitudinal direction and tapered shape areas, on both sides of the straight shape area, in which a diameter gradually decreases toward ends in the longitudinal direction, and wherein the elastic layer has, in a central portion in the longitudinal direction thereof, a straight shape area having a substantially uniform diameter along the longitudinal direction and inverted crown shape areas, on both sides of the straight shape area, in which a diameter gradually increases toward ends in the longitudinal direction. This configuration allows to prevent defects in image heating while suppressing creases in the recording material.

    摘要: In continuous printing operation which repeatedly sets a state in which when a preceding printing material passes through the nip area of a thermal fixing unit, a succeeding printing material has been supplied to an image forming unit and image forming operation has been started, a first temperature indicating an ambient temperature near the thermal fixing unit is measured at an early time point in the continuous printing operation. A second temperature indicating the temperature of the printing material which has passed through the press contact nip portion at a predetermined period of time during the continuous printing operation is measured. The amount of heat to be supplied to the succeeding printing material is controlled on the basis of the measured first and second temperatures.
