Abstract
Liquid toners are generally recognized as being capable of providing sharper electrophotographic images, but have been found to provide less than desirable results in multicolor imaging processes. The selection of a unique combination of (a) the ratio of conductivities between the toner liquid and the total toner composition, and (b) the zeta potential of the toner particles in the carrier liquid have been found to provide unique benefits to the quality of the liquid tone multicolor images.
