Magenta toner
The magenta toner is excellent in image density, has an enhanced chargeability, and can be produced at a low cost. The magenta toner includes a binder resin and a magenta colorant. A compound A represented by the following general formula (1) and C.I. Solvent Violet 59 are contained as the magenta colorant.
1. A magenta toner comprising a binder resin and a magenta colorant,
wherein a compound A represented by the following general formula (1) and C.I. Solvent Violet 59 are contained as the magenta colorant, and
wherein a total content of the compound A and the C.I. Solvent Violet 59 is from 3 to 30 parts by mass with respect to 100 parts by mass of the binder resin, and a mass ratio of the content of the compound A to the content of the C.I. Solvent Violet 59 (compound A/C.I. Solvent Violet 59) is from 0.8 to 20:
where R 1 is a hydrogen atom, an alkyl group or an alkoxy group;
R 2 is a hydrogen atom, a halogen atom or an alkoxy group;
R 3 is a hydrogen atom, a halogen atom, an alkoxy group or a nitro group;
R 4 is a hydrogen atom, a halogen atom or an alkoxy group;
R 5 is a hydrogen atom, a halogen atom or a primary amide group (—CONH 2 ); and
R 6 is a hydrogen atom, a halogen atom, a phenylaminocarbonyl group (—CONHC 6 H 5 ), a primary amide group (—CONH 2 ), —CONHC 6 H 4 -(p)CONH 2 or —SO 2 (C 2 H 5 ) 2 .
