Abstract
An electrophotographic electro-conductive member comprising an electro-conductive mandrel and an electro-conductive elastic layer on the electro-conductive mandrel, wherein the electro-conductive elastic layer has an elastic coefficient of 1 MPa or more and 100 MPa or less, as well as a matrix containing first rubber and a plurality of electro-conductive domains dispersed in the matrix. Each of the electro-conductive domains contains an electro-conductive particle, and the electro-conductive elastic layer includes regions containing second rubber in the circumferences of the electro-conductive domains. The matrix has an elastic coefficient R, the regions containing second rubber have an elastic coefficient R, and the elastic coefficients Rand Rsatisfy a relationship: R<R.
