Abstract
PURPOSE: To form the electrostatic charge image toner which has stable negative polarity and is superior in fluidity, non-cohesiveness and impact resistance by using the specific terpolymer.
CONSTITUTION: The toner binder contained with about 40wt% or more of the copolymer resin (preferably block polymer of molecular weight; 5000 to 50000, softening point; 80 to 160°C) of styrene base monomer such as styrene, vinyl tonlene, etc. about 40 to 80%, maleic acid base monomer such as maleic acid, maleic acid anhydride, etc. about 5 to 40% and acrylic base monomer such as (metha)acrylate ester about 10 to 50% is used and is compounded with libricants, coloring agents, etc., whereby the electrostatic charge image toner is formed. If it is desired to form the magnetic toner, adding magnetic fine particles of about 0.1 to 5μ to the above compound suffices.
