ABSTRACT:
A direct electrostatic printing device for printing an image onto an image receiving substrate includes a toner carrier having a plurality of charged toner particles thereon. A toner delivery unit conveys the charged toner particles to the toner carrier. The toner delivery unit further includes a voltage source and a transfer member connected to the voltage source. The voltage source produces an electrical potential difference between the transfer member and the toner carrier to cause toner particles having a predetermined charge polarity to be attracted from the transfer member to the toner carrier. A printhead structure has an electric field pattern generated on it which is defined by an image to be printed. The printhead structure selectively controls transport of charged toner particles from the toner carrier onto the image receiving substrate.
