Abstract:
A fixing apparatus includes a roller, a heating rotation member configured to form a pressure portion by coming into contact with the roller, the heating rotation member being rotated by rotation of the roller, and a pressing rotation member configured to form a nip portion by coming into contact with the roller, the pressing rotation member being rotated by the rotation of the roller, wherein micro-hardness of a surface of the heating rotation member at the pressure portion and micro-hardness of a surface of the pressing rotation member at the nip portion are both higher than micro-hardness of a surface of the roller, and wherein frictional force acting on the roller at the pressure portion is larger than frictional force acting on the roller at the nip portion.
