发明名称 LIQUID DEVELOPER
摘要 <p>It is an object of the present invention to provide a liquid developer in which, in liquid developers for electrophotography or electrostatic recording, the adverse effect on electric resistance of the liquid developer and the electrically charged characteristics of toner particles is minimized and the dispersibility of a pigment and the dispersion stability of the toner particles are improved. The present invention relates to a liquid developer, which is obtained by dispersing colored resin particles encapsulating a pigment in an insulating hydrocarbon organic solvent by a wet-grinding method using a dispersant, wherein the dispersant is a polyester side chain-containing carbodiimide type compound formed by introducing a polyester side chain into a molecule of a carbodiimide compound through a reaction with a carbodiimide group.</p>
