    摘要: A process for the preparation of polymer compositions which comprises mixing a conductive component with an anionic polymeric latex containing a polymer; adding a cationic surfactant, or flocculant whereby the aggregation of the latex particles and the conductive component particles results; subsequently adding colloidal stabilizer, followed by the addition of a base to obtain a pH of from about 7 to about 12; heating above about the polymer glass transition temperature thereby enabling the severage, or breakage of the formed aggregated particles; further heating above about the polymer glass transition temperature enabling the coalescence of the polymer and conductive component particles; and optionally washing and drying the resulting coalesced product.

    摘要: A color image forming machine is provided having a plurality of xerographic marking engines, each forming associated color separations that are combined to produce a color print image. Each marking engine includes a dual replenisher assembly having first and second reservoirs containing respective toners of different gloss levels. The reservoirs each include one or more augers separately and independently controlled for dispensing the respective toners into a developer to continuously vary the gloss level of the toner in the developer.
