Abstract
A fixing device includes a hollow cylindrical sleeve provided to surround a hollow glass roller containing a halogen heater therein, and a pressure roller that contacts and presses the glass roller and the sleeve. The glass roller is made of an infrared-transparent material. The sleeve has an inner diameter larger than the outer diameter of the glass roller and it is heated by absorbing infrared rays from the halogen heater. The pressure roller nips and holds the sheet carrying the toner between itself and the glass roller and as the sleeve.
