Abstract:
[Object] The purpose of the present invention is to provide a charge control agent for polymerized toners and particularly for color toners, which has a large charge amount and environmentally stable charging characteristics. [Solving Means] Since a charge control agent including a pyrazolone derivative represented by a general formula (1) or a salt of the derivative as an active ingredient has a large charge amount and excellent environmental stability of charging, it has an excellent charge-imparting effect for use in polymerized toners and particularly in color toners. (in the formula, R 1 , R 2 , and R 3  each independently represent a substituted or unsubstituted C1 to C20 linear or branched alkyl group, a substituted or unsubstituted aromatic hydrocarbon group, or a substituted or unsubstituted condensed polycyclic aromatic group.)

Claim (Index 3):
The charge control agent according to  claim 1 , wherein in the general formula (1), R 1 , R 2 , and R 3  each independently represent a substituted or unsubstituted aromatic hydrocarbon group.
