<p>PURPOSE:To maintain a color picture excellent in picture quality such as picture density and fogging and on which a toner is not scattered in high-speed printing or repeated use by incorporating specified binder resin, charge control agent and colorant. CONSTITUTION:This toner contains a binder resin contg. a cross-linking component, a charge control agent contg. a non-metallic quaternary ammonium salt anti a metal-contg. quaternary ammonium salt and a colorant. A resin contg. a cross-linking component is used from the standpoint of durability, etc., and especially a styrene-acrylic resin is preferably used from the viewpoint of the toner characteristic. At least two kinds of charge control agents, e.g. a nonmetallic quaternary ammonium salt and a metal-contg. quaternary ammonium salt with the anion part being of metallic complex structure, are added into the toner. Molybdenum is preferably used as the metal atom of the metal-contg. quaternary ammonium salt from the standpoint of the charge characteristic and tone. Further, a combination of an amorphous-metal photoconductive material-contg. photosensitive body and a develop consisting of the electrostatic charge image developing color toner and carrier is preferably used.</p> |
