Title: Novel electrostatic imaging system

Abstract: An electrostatic imaging system in which a conductive pattern and triboelectric charging are utilized on opposite sides of an electrically insulating member to form a developable electrostatic latent image. Electrostatically charged marking particles are deposited in conformance to the latent image and thereafter transferred to a receiving sheet. Charging, development and transfer are effected without the aid of light or any externally applied voltage.
