Casing for transporting a toner mixture and method for producing a casing of this type

摘要

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.
