A conductive rubber roller comprising a conductive core material and provided thereon a rubber layer; the rubber layer being formed by using a rubber composition containing as rubber components at least a polar rubber and an ethylene oxide-propylene oxide-allyl glycidyl ether terpolymer; the ethylene oxide-propylene oxide-allyl glycidyl ether terpolymer having a melt peak temperature of from 20 to 30° C. and a melt enthalpy change &Dgr;H of from 40 to 70 mJ/mg as measured with a differential scanning calorimeter; and the allyl glycidyl ether in the ethylene oxide-propylene oxide-allyl glycidyl ether terpolymer being in a copolymerization ratio of from more than 10 mol % to 20 mol % or less.
