Rubber member for paper feed device
 An apparatus feed paper sheets to a photosensitive dram of an electronic copier, negatively charged toner adhering the dram. The apparatus incorporates a paper feed roller and a rubber member located adjacent the roller for supporting paper sheets in contacting relation to the roller. The robber member has a polymer, vulcanizer, vulcanization aid and filler; and at least one component selected from the group consisting of magnesium oxide, barium oxide, nylon short fibers, powder of nylon short fibers and nigrosine compound. The component is present in an amount of 1 to 100 parts by weight to 100 parts by weight of the polymer. The paper sheet becomes electrostatically charged negatively, when contacting the rubber member during sheet feeding by the roller, thus preventing electrostatic attraction between the paper approaching the dram and negatively charged toner on the dram.
