Abstract
A toner applicator for delivering an optimum amount of toner powder to a recording electrode of an electrographic recording system whereby a portion of said toner may be electrographically deposited on a recording medium in the form of toner images. The toner is fed from a toner reservoir onto the recording medium in a relatively uniform layer by a toner supply means that is adjustable to vary the thickness of the toner layer deposited on the recording medium. The toner layer is then transported on the recording medium to the recording electrode, and a magnetic field is induced in the recording electrode to draw the toner layer into a position bridging between the recording electrode and the recording medium for being redeposited on the recording medium in the form of toner images.
