Abstract
A direct imaging method wherein a recording electrode comprising a plurality of electrode styli and a magnetic toner developer are provided on opposite sides of an insulating recording medium, such that an image is printed on the recording medium through direct adherence of magnetic toner on the recording medium when a voltage is applied across the recording electrode and magnetic toner developer. A proper gap discharge is generated between the recording electrode and the recording medium by forming a very narrow gap between the recording electrode and the recording medium. The present invention also comprehends adhering charges to the rear side of the recording medium by means of such gap discharge and the magnetic toner of the magnetic toner developer is reliably held to the surface of the recording medium by means of such charges.
