Disclosed is a charge control agent that has high compatibility with a toner resin, has a quick rise in charge, exhibits excellent charging characteristics, and can be easily manufactured. The charge control agent has the following chemical formula (3), which is one component of the monomer: wherein R1 is independently the same or different and includes a hydrogen, hydroxyl group, halogen, carbooxy-containing group, C1 to C18 is a linear or branched alkyl group, or C1 to C18 is a linear or branched alkoxy group, R2 is a hydrogen, hydroxyl group, halogen, carbooxy-containing group, or C1 to C18 is a linear or branched chain. Or a C1-C18 linear or branched alkoxy group, g is a number from 1 to 3, h is a number from 1 to 3, M is hydrogen, an alkali metal, C1 to C18 is a straight chain or It contains a charge control resin obtained by copolymerizing a styrene derivative represented by a branched alkyl group, an ammonium atom group and a mixture thereof and a vinyl group-containing monomer as an active ingredient. That. [Selection figure] None |
