发明名称 LIQUID DEVELOPER
摘要 An object of the present invention is to provide a liquid developer for electrophotography or electrostatic recording, wherein such liquid developer achieves good electrophoretic migration property as well as good transferability onto a base material for printing. As a means for achieving the aforementioned object, the present invention provides a liquid developer obtained by dispersing, in an insulating solvent, colored resin particles obtained according to the coacervation method from at least a pigment, pigment dispersion agent and binder resin, wherein the insulating solvent has been mixed in such a way that aliphatic hydrocarbon solvent having 11 to 12 carbon atoms accounts for 8.0 to 20.0 percent by mass, and aliphatic hydrocarbon solvent having 17 to 30 carbon atoms accounts for 2.0 to 45.0 percent by mass, and a total of these aliphatic hydrocarbon solvents having 11 to 30 carbon atoms accounts for 99 percent by mass or more, relative to the total mass of insulating solvent, and also in such a way that the viscosity of the insulating solvent at 25°C becomes 2.0 to 10.0 mPa€¢s.
