Abstract

An electrophotographic member including a substrate, and an elastic layer on an outer peripheral surface of the substrate; wherein the elastic layer has silicone rubber, a tensile modulus of the elastic layer in a direction perpendicular to a thickness direction thereof is 0.20 MPa or less, a compressive modulus of the elastic layer in the thickness direction is 0.19 to 0.57 MPa, a value (tensile modulus/compressive modulus) of a ratio of the tensile modulus of the elastic layer in a direction perpendicular to the thickness direction, relative to the compressive modulus of the elastic layer in the thickness direction, is 0.80 or lower, and a rate of decrease of each of the compressive moduli of the samples from the elastic layer in a direction corresponding to the thickness direction of the elastic layer is 5% or lower.
