Electrophotographic fixing member and manufacturing method thereof, fixing apparatus, and electrophotographic image forming apparatus

摘要

An electrophotographic fixing member is provided, which is excellent in toner releasability and hard to change in rubber elasticity of a silicone rubber elastic layer. The fixing member is laminated with a substrate, a cured silicone rubber layer, a cured silicone rubber adhesive layer and a fluorine resin layer, wherein when infrared light absorption strength ratios (1020 cm−1/1260 cm−1) at 1020 cm−1 and 1260 cm−1 determined by sampling the portions of 5 μm and 20 μm from the outer surface of the cured silicone rubber layer are taken as α(5) and α(20), respectively, a relationship of α(5) and α(20) satisfies 1.03≦̸α(5)/α(20)≦̸1.30 and α(20) is 0.8 or more and 1.2 or less.
