Abstract
A cylindrical fixing member includes a substrate; an elastic layer overlying the substrate; an outermost surface release layer overlying the elastic layer; and a heat source inside. The elastic layer includes a carbon fiber and has a heat diffusivity (X) not less than 1.0×10−6 m2/s in a direction of a rotational axis of the fixing member, and the heat diffusivity (X) is not less than 2.0 times of a heat diffusivity (Z) in a direction of thickness of the elastic layer.
