Black toner particles and printing methods

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&#xb0; 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&#xb0; 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.

Imaging apparatus and improved toner therefor

Liquid toner and method of printing using same

A toner particle adapted for use in electrostatic image formation, comprising a polymer and flakes of metal dispersed in the polymer.

Toner material and method utilizing same

A liquid toner comprising: a carrier liquid; and toner particles dispersed in the carrier liquid, said toner particles comprising: a polymer blend comprising: a first polymer comprising a minor portion of said blend and having a relatively higher chemical reactivity with paper; and a second polymer comprising a major portion of said blend and having a relatively lower or null chemical reactivity with paper.
