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