发明名称 Liquid developer
摘要 It is an object of the present invention to provide a liquid developer in which in liquid developers for electrophotography or electrostatic recording obtained using the coacervation method, electric resistance of the liquid developer and the electrophoretic property or the charging characteristic of the toner particles are adequately maintained, and the dispersibility of a pigment and the dispersion stability of the toner particles are good. A liquid developer formed by dispersing colored resin particles comprising at least a pigment, a dispersant and a resin in a hydrocarbon insulating medium using a coacervation method, wherein said dispersant is a carbodiimide compound having at least one basic nitrogen-containing group and at least one polyester side chain introduced through a reaction with a carbodiimide group in its molecule, and said resin is an acid group-containing resin and the acid value of the resin is 1 to 100.
