Abstract

PURPOSE: To make friction charging with carrier particles easy and rapid and faithfully reproduce originals without changing the color tones of three primary colorings of cyan, magenta and yellow by using the specific non-gel-form polymer for a binding resin.
CONSTITUTION: The monomer component which is selected from addition polymerizable unsaturated aliphatic carboxylate such as styrene (derivative) and butyl methacrylate and which preferably does not include polar groups or functional groups such as OH, amino, amide, epoxy, etc. in molecules and the addition polymerizable unsaturated carboxylic acid such as of acrylic acid of the weight parts satisfying the relations of the formula in 100pts. wt. of the monomer component of the resultant polymer are copolymerized. The resultant non-gel form polymer is made of less than 10% of its free carboxylic groups to hydrophobic metal salt and is then melted and kneaded together with coloring agents and, if necessary, assistants, after which the mixture is ground and classified.
