ABSTRACT:
The invention relates to a liquid toner and imaging apparatus provided with an imaging surface having a liquid toner image formed thereon on fibrous toner particles and carrier liquid. The fibrous toner particles can be composed of a polymer portion and pigment dispersed therein, where the polymer portion comprises a surface of the fibrous toner particles and is insoluble in the carrier liquid at temperatures below 40° C., so that the polymer portion will not dissolve or solvate in storage. The polymer portion also is solvatable by the carrier liquid only at temperatures above 50° C. The carrier liquid has, as a major component, first liquid hydrocarbon having a first rate of evaporation, and, as a minor component, second liquid hydrocarbon having a second rate of evaporation which, at room temperature, is at least an order of magnitude less than the first rate of evaporation.
