A contact cleaning roller or belt fabricated by attaching a polymer-coated flexible substrate cut from flexible sheet stock to the surface of a structural core or a structural belt of a desired length. For either a CCR or CCB, an adhesive and/or resilient layer may be inserted between the flexible substrate and the structural element. The flexible substrate may be formed of metal, for example, aluminum, or plastic, for example, polyethylene terephthalate and may comprise, for example, a toothed belt having a smooth outer surface. The flexible substrate is provided with a polymeric layer having low durometer and triboelectric properties, such as novolak resin, cross-linked epoxides, polyisoprene rubber, silicone rubber, polyurethane, and norbornene-co-styrene-co-maleic anhydride. An advantage of a CCR or CCB in accordance with the invention is that the substrate and polymeric layer are easily replaced to provide a refurbished CCR or CCB.
