PROBLEM TO BE SOLVED: To provide an electro-conductive rubber member which ensures a small rise of resistance in continuous energization, no contamination of an electrophotographic photoreceptor and such a small electric variation as to achieve electric uniformity, and a transfer member and a transfer roller comprising the electro-conductive rubber member. SOLUTION: In the electro-conductive rubber member used in an electrophotographic process, a vulcanized foamed rubber layer of the electro-conductive rubber member contains an additive from which water is generated by thermolysis and vulcanization foaming treatment for the vulcanized foamed rubber layer is high-frequency molecular vibrational heating.
