Abstract
An electrographic stylus recording apparatus wherein magnetically attractable toner material is moved from a toner material dispensing apparatus to a nonrotatable cylindrical sleeve bearing an imaging stylus array where a rotatable magnetic means within the sleeve functions to move the toner material to the stylus array with excess and nonimaging toner continuing to a flange means on the sleeve which directs the toner material to at least one chute for return to the toner dispensing apparatus. Electrical conductors for the stylus array extend from the stylus array and about the sleeve to a position between the flange means and the toner dispensing means where the conductors are positioned to extend outwardly in a generally radial direction from the sleeve for connection to driver circuits.
