Abstract
Provided is a toner, comprising a toner particle having a core-shell structure composed of a core particle and a shell phase on a surface of the core particle, the core particle containing a resin X and a colorant, the shell phase being derived from a resin fine particle containing a resin Y, in which a relationship among a SP value of the resin X, a SP value of the resin Y, and a SP value of an organic solvent falls within a specific range, and a relationship between a number-average particle diameter of the resin fine particle when the resin fine particle is dispersed in water and a number-average particle diameter of the resin fine particle when the resin fine particle is dispersed in the organic solvent falls within a specific range.
