ABSTRACT:
A roller is characterized by an inexpensive and disposable construction for use in transporting and applying developer material in a developer system of a xerographic copier machine, and a method of fabricating such rollers. The rollers have an outside electrically-conductive surface for transporting and applying developer material and are constructed of a tubular fiber core, preferably spirally-wound and laminated paper plies, with an outside surface ply of aluminum foil spirally-wound on and laminated to the fiber core. At least those rollers which are utilized as applying rollers have spaced-apart grooves formed in the outside surface of the roller and formed therein without tearing or cracking the thin aluminum surface ply.
