Beschreibung
Zusammenfassung:	Provided is a fixing member for electrophotography, which has a configuration wherein a fluororesin layer is bonded onto a cured silicone rubber layer with use of an addition-curable silicone rubber adhesive, and which is capable of more stably maintaining the elasticity of the cured silicone rubber layer and provides electrophotographic images with stable quality. A fixing member for electrophotography according to the present invention comprises a base, a cured silicone rubber layer, and a fluororesin layer that is bonded onto the cured silicone rubber layer. This fixing member for electrophotography is characterized in that: if Hµ0 is the microhardness of a cured silicone rubber that constitutes the cured silicone rubber layer and Hµ1 is the microhardness of the cured silicone rubber that is cured after being immersed in a methyl hydrogen silicone oil for 24 hours, Hµ1/Hµ0 is from 1.5 to 5.0 (inclusive); and the cured silicone rubber layer contains a titanium oxide crystal having an anatase structure.
