ABSTRACT:
To provide for adhesion of toner particles on a latent image on a ferroelectric material substrate, the toner is so constituted that, upon being transported in close proximity to the ferroelectric substrate, the toner will shape itself into a wave to form a hydraulic meniscus, so that the toner will be adhered by hydraulic meniscus toning. The toner must have low electrical conductivity and is so formulated that particles are kept as discrete entities without interconnection to each other by mechanical or electrical binding. The toner materials can be acrylics, acrylic copolymers, polyethylene, polyethylene vinylacetate copolymers; suitable solvents are aliphatic solvent soluble rosin, rosin esters, rosin ester derivatives, phthalate esters and abietic acid esters; the thermoplastic polymer should be soluble in the dispersant between about 90.degree. C. to 100.degree. C., but insoluble at ambient temperature, and the plasticizer is soluble in the dispersant at both elevated and ambient temperature.
