Abstract
A casing is provided for transport of a toner mixture on its outer surface in a development device. An outer surface of a metal casing is chemically pre-treated. In a subsequent chemical deposition, a nickel-copper-phosphor layer is generated on the outer metal casing surface. The layer comprises 1 to 2% copper and 8 to 10% phosphor and the remainder comprises substantially nickel.

A casing for transport of a toner mixture on its outer surface in a development device, said casing having a wall substantially comprised of an electrically-conductive material, and an outer surface of the wall bearing a layer comprised of nickel-copper.
A method for production of a casing for transport of a toner mixture on its outer surface in a development device, comprising the steps of:
- chemically pre-treating an outer surface of a metal casing;
- and
- in subsequent chemical deposition generating a nickel-copper-phosphor layer on the outer surface of the metal casing, the layer comprising 1 to 2% copper and 8 to 10% phosphor and a remainder comprises substantially nickel.
