Positive Electrified Charge Control Agent and Positive Electrified Toner for Developing Electrostatic Image

摘要

The positively charged charge control agent is represented by the following general formula (I);Or the following formula (II);(In formulas (I) and (II), [D- (SO ₃ ) ₂ ] ^2- is a divalent anion of an organic acid having at least two sulfonic acid groups, p = 0 or 1, and B is p = 0. When p = 1, a carbon atom or a nitrogen atom, J is a carbon atom or a nitrogen atom, A is an organic group which forms a ring together with (B) p and J, two R are the same or different organic groups And the silicon complex compound represented by group) which may form a heterocycle as an active ingredient. The positively charged toner for developing electrostatic images contains this positively charged charge control agent. The charge control method of the electrostatic toner for electrostatic image development is to charge this toner positively by friction.;Electrostatic Toner, Charge Control Agent, Silicon Complex Compound
