Abstract
A cylindrical sleeve suitable for holding and conveying image forming toner particles is provided by a hollow cylinder of a non-magnetic material the exterior surface of which is texture by sand blasting and then by electrolessly coating the hollow cylinder with a durable uniform thin layer of an alloy of molybdenum, nickel and phosphorus. The interior of the hollow cylinder contains a magnet capable of generating a magnetic field sufficient to hold toner particles on the surface of the cylindrical sleeve.
