Electrographic printing apparatus for forming a toner image on a recording medium, includes: a magnetic brush having a rotatable magnetic core and a stationary outer shell; a developer supply for supplying a magnetic developer powder including toner to the magnetic brush. A print head on the outer shell forms a plurality of parallel lines of developer. Toner is selectively transferred from a plurality of electrodes within each line to a receiver. A receiver electrode is arranged in spaced relation to the print head to define a recording region through which the receiver can be moved.
