Abstract
The present invention is directed to providing a fixing member that has a flexible surface and that can supply a larger amount of heat to a material to be recorded and a toner in a shorter period of time. The fixing member comprises a substrate, an elastic layer and a releasing layer, wherein thermal effusivity in a depth region from a surface of the releasing layer is 1.5 [kJ/(m2·K·sec0.5)] or more, the depth region corresponding to a thermal diffusion length when an alternating-current temperature wave having a frequency of 10 Hz is applied to the surface of the releasing layer, and a surface micro rubber hardness is 85 degrees or less.
