Abstract
Disclosed is an electric conductive roller comprising a rubber having a volume specific resistance of not more than 10.sup.12 .OMEGA.cm and an electric conductive filler mixed in the rubber, said electric conductive roller satisfying the following formulas (1) and (2): EQU log R.gtoreq.log R.sub.0 -4 (1) EQU log R<log R.sub.0 (2) wherein R is a resistance of the roller when the electric conductive filler is added, and R.sub.0 is a resistance of the roller when no electric conductive filler is added. This electric conductive roller has a low dependence of an electric resistance on a change in applied voltage and environment.
