Abstract
Provided is an electrophotographic member, the member including an elastic layer that is formed by graphite particles dispersed in a silicone rubber and has high thermal conductivity in the thickness direction. The electrophotographic member has a substrate and an elastic layer on the substrate, in which the elastic layer contains a cured product of an addition-curable liquid silicone rubber mixture including graphite particles, the dibutyl phthalate (DBP) oil absorption number of the graphite particles is from 80 cm/100 g to 150 cm/100 g, the thermal conductivity in the thickness direction of the elastic layer is from 1.1 W/(m·K) to 5.0 W/(m·K), and the modulus in tension of the elastic layer is from 0.1 MPa to 4.0 MPa.
