Here is provided a charge control resin which is prompt in charge rising up, excellent in electrostatic charging propensity and easy in manufacturing. This charge control resin contains a polymer as an active ingredient having a constituent unit represented by following Formula (1)
in the Formula (1), R
1
is independent of one another, and is a hydrogen atom, a hydroxyl group, a halogen atom, a carboxy-containing group, a straight-chained or branched alkyl group having 1-18 carbon atoms, or a straight-chained or branched alkoxy group having 1-18 carbon atoms; R
2
is a hydrogen atom, a hydroxyl group, a halogen atom, a carboxy-containing group, a straight-chained or branched alkyl group having 1-18 carbon atoms, or a straight-chained or branched alkoxy group having 1-18 carbon atoms; g is a number of 1-3; h is a number of 1-3; and M is a hydrogen atom, an alkali metal, a straight-chained or branched alkyl group having 1-18 carbon atoms, an ammonium radical or a mixture of any of these.
