A power transmission belt having a conductive rubber mixture, which has a resistivity of less than 6.0 M, wherein the conductive composition includes a base rubber, 25 to 250 phr of non-conductive carbon black as a filler and up to 5 phr of graphene as a conductive filler. The incorporation of a combination of a non-conductive carbon black filler and graphene into the rubber mixture allows for the replacement of conductive carbon black, which is conventionally used to procure conductive properties to rubber, but which has the disadvantage that it is comparatively expensive, especially in the quantities needed to confer conductive properties to the rubber mixture.
