Abstract
A method of producing a liquid developer for electrostatic images by subjecting a low density polymer to a solvent of relatively smaller molecular size so that the solvent activates the polymer chains to form a modifying carrier liquid, and then applying the modifying carrier liquid to particles of solid toner material so that by dilatant action the molecular bonds of the particles are broken to produce a fine developer held in a lattice structure.
