PROBLEM TO BE SOLVED: To provide a conductive member where the increase of an electric resistance value by ordinary consecutive energizing is restrained, and simultaneously, the change of the ambient environment, in particular, the fluctuation width of the electric resistance value in the case of low temperature and low humidity and high temperature and high humidity is small as a conductive member utilized for a conductive elastic roller used in developing and transferring mechanisms or the like, for example, in an electrophotographic device. SOLUTION: As for this conductive member utilized for the conductive elastic roller used in the developing and the transferring mechanisms or the like in the electrophotographic device, a conductive elastic body 2 constituting the conductive member is a foaming body consisting of a non-polar rubber, and filler incorporating carbon black whose specific surface area X [m<2> /g] and DBP oil absorption Y [ml/100 g] by a nitrogen adsorption method are 30<=X<=60 and 140<=Y<=500 is used as conductive filler. |
