Abstract (en)
An electrostatic liquid developer consisting essentially of a nonpolar liquid having a Kauri-butanol value of less than 30, an average boiling point of 150 DEG C to 400 DEG C, a boiling point range of less than 12 DEG C, and a viscosity of less than 20 cps at 30 DEG C; thermoplastic resin particles having an average by area particle size of less than 10 mu m; and a nonpolar liquid soluble ionic or zwitterionic charge director compound.
