Abstract
A fixing apparatus that fixes, on a transfer material, toner images on the transfer material through heating and pressing, wherein, a ray-radiating member that radiates rays is provided, and a roll-shaped rotary member for applying heat is formed by providing a cylindrical ray-transmitting base member which can transmit the rays and a cylindrical ray-transmitting elastic layer or a ray-transmitting heat insulating layer which can transmit the rays, and by providing, on the outer side of the ray-transmitting elastic layer or the ray-transmitting heat insulating layer, a ray absorbing layer that absorbs the rays stated above. The inequality of T1<T2<T3 holds when T1 (°) represents an average temperature in the layer of the ray-transmitting base member, T2 (°) represents an average temperature in the layer of the ray-transmitting elastic layer or the ray-transmitting heat insulating layer, and T3 (°) represents an average temperature in the layer of the ray absorbing layer during a warm-up.
