FIXING MEMBER FOR ELECTROPHOTOGRAPHY, METHOD FOR PRODUCING THE SAME, FIXING DEVICE, AND ELECTROPHOTOGRAPHIC IMAGE FORMING APPARATUS

Document Type and Number:

WIPO Patent Application WO/2008/075753

Kind Code:

A1

Abstract:

Disclosed is a fixing member for electrophotography, which is excellent in toner releasability, while comprising a silicone rubber elastic layer whose rubber elasticity is hardly changed. Specifically disclosed is a fixing member wherein a base, a cured silicone rubber layer, a cured silicone rubber adhesive layer and a fluororesin layer are arranged in layers. This fixing member is characterized in that when the infrared absorption intensity ratios between at 1020 cm-1 and at 1260 cm-1 (1020 cm-1/1260 cm-1) of samples taken from a portion at a distance of 5 μm from the outer surface and a portion ata distance of 20μm from the outer surface are respectively expressed as α(5) and α(20), the α(5) and α(20) satisfy the following relation: 1.03 ≤ α(5)/α(20) ≤ 1.30 and α(20) is not less than 0.8 but not more than 1.2.
