Fixing apparatus with a ray transmitting device inside one roller |
摘要 |
The fixing apparatus fixes a toner image on a transfer material by applying heat and pressure onto the transfer material. It uses a roll-shaped rotary member for applying heat. The roll-shaped rotary member has a ray radiating device for radiating heat rays inside a cylindrical ray-transmitting base member. A cylindrical ray-transmitting elastic/insulating layer is on the base member and a heat ray absorbing layer is provided on the elastic/insulating layer. The difference between the heat ray absorbing ratio (%) per unit thickness (mm) in the base member and that in the ray-transmitting elastic/insulating layer is made not more than 20%. The fluctuations of thickness in the base member and the elastic/insulating layer are equal to, or not more than, 0.1 mm.
