摘要： A method is described for the preparation of electrostatographic toner particles which involves the use of carnauba wax for treating the surface of a pigment employed The method involves recrystallizing carnauba wax from its natural state by dissolution in ethyl acetate and cooling to precipitate needle like structures The structures so obtained are then added to a mixture comprising a pigment, a polymer material, a solvent and optionally a charge control agent which mixture serves as the organic phase in a limited coalescence process. The toner particles produced in accordance with this method are non spherical in nature and evidence excellent fluidity and anti-blocking properties.

摘要： An improvement in the method and apparatus for producing a multi-color electrophotographic image wherein an electrophotographic medium is mounted on a carrier therefor and is translated over a predetermined path so that the medium is first charged, then exposed to a first light-borne image and then toned. Thus, the unexposed portions of the image bearing charged region of the medium are toned, preferably by a liquid toner, to produce a first color visible image. The carrier is then returned to the first position to repeat the foregoing steps to charge the medium and to expose it to a second light-borne image and to tone the second image with a second toning element to produce a second color visible image on the same sheet of medium. One of the images formed is a cyan image. The improvement comprises the steps of: developing the cyan image with a self-fixing, liquid electrographic developer comprising a volatile, electrically insulating liquid carrier and, dispersed in said carrier, (i) toner particles comprising a polymeric binder, cyan pigment and a dispersing agent and (ii) wax particles, and then buffing the surface of the cyan image with a relatively coarse, stiff, and rough fibrous brush member after the cyan developing step and prior to the next charging step to prevent small toner particles present in liquid toner from adhering to the cyan image and thereby contaminating the cyan image and whereby the cyan image does not flake off or smear during the buffing step.
