Magenta toner and method for producing the same

A method for producing a magenta toner comprising the steps of:

• mixing a compound represented by a formula (1) and a pigment having a quinacridone skeleton with an organic solvent to prepare a colorant dispersion;
• mixing the colorant dispersion with a polymerizable monomer to prepare a polymerizable monomer composition;
• dispersing the polymerizable monomer composition in a water-based medium and granulating the polymerizable monomer composition to produce droplets of the polymerizable monomer composition;
• and
• polymerizing the polymerizable monomer in the droplets to produce a magenta toner particle, wherein
• a toner to be obtained is a magenta toner comprising magenta toner particles, each of which comprises a binder resin, the compound represented by the formula (1), and a colorant, and the colorant comprises a pigment having a quinacridone skeleton:
• wherein R1 and R2 each independently represent a hydrogen atom, an alkyl group, an aryl group, or an aralkyl group, and
• the amount of the compound represented by the formula (1) is 0.01 to 10 part by mass based on 100 parts by mass of the pigment having a quinacridone skeleton.
