摘要： The present invention relates to methods of drying and recovering toner particles from a liquid carrier. The methods are very effective to generate discrete, substantially non-agglomerated dry toner particles in a manner that preserves the particle size and particle distribution of the wet particles. The resultant dried toner particles free-flowing with a relatively narrow particle size distribution. The present invention uses electrical phenomena to help transfer charged toner particles from a liquid carrier onto a substrate surface. In practical effect, the particles are electrically plated onto the surface. Because the resultant coating has a relatively large drying surface area per gram of particle incorporated into the coating, drying may occur relatively quickly under moderate temperature and pressure conditions. After drying, the dried toner particles are readily recovered and may then be used in dry or even wet toners for electrophotographic applications.

摘要： A method of producing an image on a final image receptor from image data in a multiple pass electrophotographic system is provided. The method comprises the steps of applying transfer assist material to an intermediate transfer member and providing at least one development unit comprising a photoreceptive element and charged toner particles. During each complete processing cycle of an intermediate transfer member, a toned image is created and transferred to the intermediate transfer member by application of a bias. In multiple processing cycles of the intermediate transfer member, the transfer assist material and the at least one toned image thereby form a composite image layer on the intermediate transfer member. The method further comprises contacting the composite image layer with a final image receptor while applying a bias that is sufficiently strong to transfer at least a portion of the composite image layer to the final image receptor.
