摘要： Electrophoretic process and apparatus for developing an electrostatic charge pattern carried by a dielectric surface by progressively moving that surface through a development station and simultaneously progressively advancing a layer of liquid toner (11) comprised of toner particles dispersed in a carrier liquid, through that station in proximity to said charge-carrying surface, (3), and imposing an electric field bias to cause or promote selective image-wise movement of toner particles through said liquid at said development station and deposition thereof on said charge-carrying surface in a pattern representing said electrostatic charge pattern, wherein said layer of liquid toner contains toner particles in a concentration of from 2 to 25% by weight, and including the step of applying a film of a substantially toner-free non-polar liquid which is miscible with the carrier liquid of said liquid toner and which has a specific conductivity lower than 0.2 nS/m over said liquid toner layer (11) in such manner and at such a rate that each increment of such toner layer arrives at the development station, substantially free from turbulence and covered by the film of substantially toner-free liquid, the thickness of the film being such that at the development station it just makes contact with the chargecarrying surface.

摘要： A particulate composition of matter for magnetic brush development of electrostatic charge patterns, adapted upon mixing with magnetic carrier particles to acquire a net positive charge, which contains colorant material and thermoplastic resin binder, the colorant material comprising a salt formed from a nigrosine base and at least one carboxylic acid containing one or two carboxylic acid groups and having from 2 to 26 carbon atoms, wherein the nigrosine salt is dispersed as particles in the thermoplastic resin binder which contains a polyester derived from fumaric acid or a mixture of at least 95 mol % fumaric acid and the balance isophthalic acid and a polyol blend of propoxylated bisphenol. The charge pattern is developed by contacting the same under the influence of an applied magnetic field with a mixture of magnetic carrier particles and the particulate composition.
