Toner production method

A method for producing a toner, comprising:

• aggregating and coalescing resin particles and colorant particles in an aqueous medium to form coalesced particles, wherein
• in the aggregating and coalescing resin particles and colorant particles, adding an aggregating agent in an amount of from 5 parts by mass to 50 parts by mass, relative to the total amount 100 parts by mass of resins,
• each resin particle comprises an amorphous polyester-based resin which is a composite resin comprising a polyester resin segment being a polycondensate of an alcohol component comprising an aromatic alcohol and a carboxylic acid component, an addition polymer resin segment being an addition polymer of a raw material monomer comprising a styrenic compound, and a structural unit derived from a bireactive monomer bonding to the polyester resin segment and the addition polymer resin segment via a covalent bond, and a crystalline polyester resin, wherein each resin particle is formed by mixing the amorphous polyester-based resin and the crystalline polyester resin, or by mixing a particle comprising the amorphous polyester-based resin and a particle comprising the crystalline polyester resin,
• the colorant particles comprise a carbon black and an addition polymer of a raw material monomer comprising a styrene and an addition-polymerizing monomer comprising a polyalkylene oxide group, wherein a pH value of the carbon black is from 5 to 6.8,
• an amount of the styrene in the raw material monomer for the addition polymer in the colorant particles is at least 30% by mass, and
• a ratio by mass of the carbon black to the addition polymer in the colorant particles is from 50/50 to 95/5, and
• a degree of circularity of the coalesced particle is from 0.960 to 0.990.
