PROBLEM TO BE SOLVED: To provide an electrophotographic fixing member which is strong to wear, is highly durable, has an excellent release property to toners even under a condition of decreasing the amt. of a release agent, is capable of uniformly fixing unfixed toner images, is high in the smoothness of an image surface after fixing and provides high image quality and a fixing device formed by using the same. SOLUTION: This member is formed by having a surface layer 4 consisting of a heat resistant elastomer dispersed with inorg. fillers treated by a silane coupling agent contg. perfluoroalkyl groups. In this case, the member is used as an elastic heating roll or heating belt, etc., of the fixing device. The heating roll 1 has the constitution obtd. by forming an elastic layer 3 and the surface layer 4 on a hollow arbor 2 and is so arrange to face a pressure roller 11 in such a manner that a nip area is formed. |
