Developer station for electrographic printer or copier has developer roller provided by driven sleeve and stator with magnetic rail extending across width of intermediate carrier for latent image

摘要

The developer station has at least one developer roller (13), provided by a driven sleeve (21) and a stator (20) with a magnetic rail (22) having a width corresponding to that of the intermediate carrier (10) for the latent image. The magnetic field flux density is reduced at each edge (23) of the magnetic rail by forming a stepped bore (24) in the magnetic rail. An Independent claim for a method for manufacturing a developer roller for a developer station of an electrographic printer or copier is also included.
