摘要： Electrostatic printing apparatus including structure for delivering developer or toner particles to a printhead forming an integral part of the printing device. Alternatively, the toner particles can be delivered to a charge retentive surface containing latent images. The developer or toner delivery system is adapted to deliver toner containing a minimum quantity of wrong sign and size toner. To this end, the developer delivery system includes a pair of charged toner conveyors which are supported in face-to-face relation. A bias voltage is applied across the two conveyors to cause toner of one charge polarity to be attracted to one of the conveyors while toner of the opposite is attracted to the other conveyor.In another embodiment, a single charged toner conveyor is supplied by a pair of three-phase generators which are biased by a dc source which causes toner of one polarity to travel in one direction on the electrode array while toner of the opposite polarity travels generally in the opposite direction.In additional embodiments of the invention, a toner charging device is provided which charges uncharged toner particles to a level sufficient for movement by one or the other of the aforementioned charged toner conveyors.

摘要： A magnetic brush apparatus which minimizes the escape of toner and/or carrier particles by means of a magnetic field shaping device which minimizes the presence of magnetic lines of force projecting axially outward from the magnetic brush rollers. Examples of magnetic field shaping devices are a piece of ferro-magnetic material and a magnetic field shaping magnet.

摘要： An improved electrostatographic process wherein the imaging surface of the imaging member is treated with a lubricating effective amount of a compound selected from the group consisting of ortho-, meta-, para-phthalic acid, their corresponding metal or ammonium salts, and mixtures thereof. Controlled treatment of the imaging surfaces of the imaging member with the above compound(s) facilitates transfer of the developed image from the imaging member to a receiving sheet and removal of toner residues from the imaging surface upon cleaning. The imaging member element of the apparatus used in carrying out this process is covered with a thin film of lubricant over substantially all of its imaging surface thereby greatly improving toner transfer and removal.
