Developer station for an electrophotographic printing or copying device

Developer station for an electrographic printer or copier device, are with the pressure applied to a charge image carrier charge images of images to be printed inked with toner, - in a lying at an electric potential of the developer roller (19) is electrically charged toner (6) to the charge image carrier (11) is transported past, - is in a transport assembly for a developer mixture (17) is provided comprising carrier and toner, - which for transporting the developer mixture (17) to the developer roller (19) comprises a magnetic roller (18) with an electrically conductive roll shell (21) and an inside of the roller sleeve (21) arranged magnetic stator (20) stipulates the rolling envelope (21) the surface has an electrically insulating layer, - adjacent to the magnetic roller (18) a charging electrode (23) which as an electrode blade (24) is carried out, the height of the developer mixture (17) sets, as well as the density of the developer mixture (17) is increased and the surface of the developer mixture (17) electrically charged from the outside before this to the developer roller (19) passes, ...
