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.

Abstract: A developed electrostatic image is transferred from a support to a carrier sheet over a gap of between twenty and seventy microns. The gap is formed by dusting onto the developed electrostatic image particles of such size as to form the required gap or by providing protuberances on the insulating support, which may be a photoconductor. The protuberances on the support or the majority of dusted particles are spaced apart by four millimeters or less.
