A device for coupling the conductive layer of a film-type photoconductor sheet to a source of reference potential includes a plurality of sharp, vitreous carbon particles which are attached to an engaging member and electrically coupled to a source of reference potential, e.g. ground. The engaging member is adapted to urge the particles to penetrate the photoconductive insulator layer and form a low resistance, ohmic contact with the conductive layer of the photoconductor sheet.
