|Electrostatic Toner Conditioning and Controlling Means|
This invention is applicable to all imaging systems that require development of an electrostatic latent image, including xerographic copiers and printers, ionographic printers, and direct powder projection printers. The invention is a system for delivering electrostatic toner to an image receiving member. It includes a traveling electrostatic wave toner conveyor with a delivery segment adjacent to the image receiving member, the delivery segment including parallel traveling wave conveyor electrodes and nudging electrodes. The conveyor electrodes are connected to a source of DC-biased multiphase electric power to establish a traveling electrostatic wave in the delivery segment to move toner in a synchronous surfing mode.
