More Information
Summary:This invention provides a process for producing a liquid developer for electrophotography or electrostatic recording, produced by a coacervation method, which process can produce a liquid developer which can satisfactorily maintain charging characteristics of the liquid developer and has good dispersion stability of colored resin particles, and a liquid developer produced by the production process. The production process is a process for producing a liquid developer utilizing a coacervation method. In the production process, colored resin particles are dispersed in an insulating hydrocarbon dispersive medium in the presence of a particle dispersing agent, which is a reaction product between a polyamine compound and a self-condensation product of a hydroxycarboxylic acid, and an acid group-containing resin.
