Abstract:
An electrophotographic fixing member includes a substrate, a cured silicone rubber layer and a fluorine resin layer bonded onto the cured silicone rubber layer, wherein a micro hardness of a cured silicone rubber constituting the cured silicone rubber layer is designated as Hμ0, and a micro hardness of a rubber obtained by soaking the cured silicone rubber in a methyl hydrogen silicone oil for 24 hours and then further curing the cured silicone rubber, is designated as Hμ1, Hμ1/Hμ0 is 1.5 or more and 5.0 or less, and the cured silicone rubber layer comprises a titanium oxide crystal having an anatase type structure.
