Abstract

To provide an electrophotographic member causing less change in toner conveyance even used in a high-temperature and high-humidity environment. The electrophotographic member has an electro-conductive substrate, an elastic layer on the substrate and a coating layer on the elastic layer. The elastic layer has a first protrusion on a surface thereof on a side opposite to a side facing the substrate. The electrophotographic member has, on an outer surface thereof, a second protrusion derived from the first protrusion. The outer surface of the electrophotographic member has one or more of electrical insulating first region(s) and an electro-conductive second region. The elastic layer has an elastic modulus of 0.5 MPa or more to 3.0 MPa or less and the coating layer has an elastic modulus of 5.0 MPa or more to 100.0 MPa or less as measured in an environment of a temperature of 30°C and a relative humidity of 80%.
