ABSTRACT:
Direct Electrostatic Printer including a combination toner charging and delivery system. The combination toner charging and delivery system serves to convey well charged toner to an area adjacent an apertured printhead through which toner particles are propelled in image configuration. The system is provided with an annular channel in a generally cylindrical member through which toner laden air moves under pressure. During movement uncharged toner particles collide with a triboactive surface of the channel due to centrifugal force and become charged. The other surface delineating the channel carries a bias electrode thereon. The electrostatic field created by the bias prevents toner from colliding with the triboactive surface once it has reached a predetermined charge/mass ratio.
