LIQUID DEVELOPING AGENT AND PROCESS FOR PRODUCING THE SAME

摘要

This invention provides a liquid developing agent for electrophotography or electrostatic recording that can realize a high solid content and has excellent developing properties. The liquid developing agent is characterized in that colored chips produced by heat kneading a pigment with a thermoplastic resin are dispersed by wet pulverization in an electrically insulating hydrocarbon solvent containing at least one pigment dispersant selected from the group consisting of specific modified novolak resins(A) having an aromatic ring and a ring opened structure of an epoxy group by a hydroxycarboxylic acid-derived carboxyl group, and copolymers (B).
