A1

Abstract:

Provided is an electrophotographic member of which the rubber elasticity can be maintained stably for a long period, and which is provided with a fluororesin surface layer that is formed by melting a fluororesin powder. Also provided are: a fixing member which can make the image quality of an electrophotographic image stable; a fixing device; and an electrophotographic image formation device. An electrophotographic member comprising a base, a cured silicone rubber elastic layer, and a fluororesin surface layer produced by melting a fluororesin powder, said electrophotographic member being characterized in that a Hμ1/Hμ0 value is 2.5 to 5.0 inclusive wherein Hμ0 represents the microhardness of a cured rubber that constitutes the cured silicone rubber elastic layer and Hμ1 represents the microhardness of a product produced by immersing the cured rubber in a methyl hydrogen silicone oil for 24 hours and then curing the immersed rubber.
