Abstract
A method for producing a toner, including aggregating and coalescing resin particles and colorant particles in an aqueous medium. The resin particles contain, in the same or different particles, an amorphous polyester-based resin which is a polycondensate of an alcohol component containing an aromatic alcohol and a carboxylic acid component, and a crystalline polyester resin. The colorant particles contain a colorant and an addition polymer of a raw material monomer containing an addition-polymerizing monomer having an aromatic group. A ratio by mass of the colorant to the addition polymer in the colorant particles is 50/50 or more and 95/5 or less.
