する定着器。 The thickness of the body of the heat roller in the paper width direction is thicker in the center and gradually thinner toward both ends, and the luminous efficiency of the halogen lamp for heat source installed in the hollow part of this heat roller is determined. In the direction of paper passing width, the center part of the distribution is the maximum luminous efficiency part, the luminous efficiency is gradually decreased toward both ends to form the minimum luminous efficiency part, and then the opposite direction is formed from this minimum luminous efficiency part towards both ends. A fixing device characterized in that the luminous efficiency is increased sequentially, and intermediate luminous efficiency sections are formed at both ends.
