Disclosed are blade cleaner, transport and fusing roll articles for use in electrophotographic devices and a method for making same. The articles are comprised of polymeric material derived from a photosensitive precursor, for example, CYRELB photopolymer available from E.I. DuPont. The process for preparing the articles comprise the steps of: depositing the photosensitive precursor onto an adhesive bearing polyester backing support material; overcoating the photosensitive precursor with a negative photoresist protective layer; exposing the negative photoresist to a selectively masked or patterned ultra violet radiation source to selectively polymerize the photopolper precursor; washing or etching away, with optional mechanical assistance, the nonpolymerized photopolymer precursor with an organic solvent mixture such as isopropanol and perchloroethylene to afford relief patterns having dimensions of the desired articles; drying the relief patterns; and exposing a second time to ultra violet radiation to further dry and cureharden the article relief patterns.
