Abstract
PURPOSE:To obtain a toner having high dispersibility in a binder resin and charging positively and uniformly and to form a clear color image free from fog by adding cetyltrimethylammonium bromide to a toner. CONSTITUTION:To polystyrene, a styrene-methacrylic acid ester copolymer or other resin are added cetyltrimethylammonium bromide by 1-15wt% to the amount of the resin and a pigment or dye such as carbon black or phthalocyanine dye by 0.1- 50pts.wt. to the amount of the resin or further added additives such as colloidal silica. Since cetyltrimethylammonium bromide is colorless, by selecting the pigment or dye, a toner having a desired color is manufactured. The toner has high dispersibility in the resin and high positively charging power, and a clear copied image free from fog is formed.
