Abstract: A method and apparatus for transferring liquid toner images from an image forming surface (10) to an intermediate transfer member (40) for subsequent transfer to a final substrate (42). The liquid toner images include carrier liquid and pigmented polymeric toner particles which are essentially non-soluble in the carrier liquid at room temperature, and which form a single phase at elevated temperatures. The method includes the steps of: concentrating the liquid toner image by compacting the solids portion of the liquid toner image and removing carrier liquid therefrom; transferring the liquid toner image to the intermediate transfer member (40), heating the liquid toner image on the intermediate transfer member (40) to a temperature at which the toner particles and the carrier liquid form a single phase; and transferring the heated liquid toner image to a final substrate (42).

Abstract: A humidity tolerant charge director composition comprises a fine dispersion in a non-polar organic solvent of a charge director material comprising a molecular charge director compound and an ionic charge director compound, each being conjugated to a polymer which is insoluble in non-polar organic solvents. The charge director material is prepared by adding to a solution of a molecular charge director compound and an ionic charge director compound in a non-polar organic solvent, a monomer compound capable of polymerising to form a polymer which is insoluble in said solvent, initiating a polymerisation reaction of the monomer compound and allowing the polymerisation reaction to progress to completion.
