ABSTRACT:
The invention comprises a method of transferring a liquid-developed electrostatic image across a gap to a carrier sheet accompanied by heating of the carrier sheet, either before or after transfer, to a temperature at which the binder or polymer forming the toner particles will solvate in the liquid entrained in the transferred image to increase the density of the image. Thus temperature is above ambient temperature but below 100.degree. C. The composition comprises an insulating dispersant liquid through which is disseminated a pigmented waxy binder or polymer which is insoluble in the dispersant liquid at room temperature but will solvate in the dispersant liquid at elevated temperatures.
