Zusammenfassung:The toner feed adjustment method has the toner concentration at the developer station of the electrographic printer or copier determined via a toner marking carried by the intermediate carrier for the charge image, with regulation of the toner material to the developer station in dependence on the measured signal for the toner marking. The feed of the toner material to the developer station is increased when the toner feed drops below a minimal value. Also included are Independent claims for the following: (a) a device for toner feed adjustment in an electrographic printer or copier; (b) an electrographic printer or copier
