| titleOfInvention | Toner production method |
| abstract | The present invention relates to a method for producing a toner capable of providing a high image density and excellent charge stability, and to a toner. [1] A method for producing a toner, including: a step of aggregating and coalescing resin particles and colorant particles, wherein the resin particles contain a composite resin containing a polyester resin segment, an addition polymer resin segment which is an addition polymerized product of a raw material monomer containing 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, the colorant particles contain a colorant and an addition polymer of a raw material monomer containing a styrenic compound, the addition polymer contains a structural unit derived from the styrenic compound in the main chain, and the ratio by mass of the colorant to the addition polymer in the colorant particles is 50/50 or more and 95/5 or less; and [2] A toner containing toner particles that contain a composite resin, an addition polymer and a colorant, wherein the composite resin contains a polyester resin segment, an addition polymer resin segment being an addition polymerized product of a raw material monomer containing 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, the addition polymer is an addition polymer of a raw material monomer containing a styrenic compound, and contains a structural unit derived from the styrenic compound in the main chain, and the ratio by mass of the colorant to the addition polymer is 50/50 or more and 95/5 or less. |
