    摘要： To provide a toner including a binder resin and colorant and is granulated in aqueous medium, wherein the binder resin is a polymer having a polyester skeleton, the polyester skeleton is obtained by block copolymerization of a polyester skeleton A in which at least a constituent unit in which CH3—C*—H(—OH)(COOH) is dehydration condensed is contained in a repeated structure and a polyester skeleton B in which a constituent unit in which CH3—C*—H(—OH)(COOH) is dehydration condensed is not contained in a repeated structure, and an optical isomer ratio X (%) (monomer equivalent) is 80% or less, where the optical isomer ratio X (%)=|X (L-type)−X (D−type)| where X (L-type) denotes a ratio (%) of L-type (lactic acid monomer equivalent) and X (D-type) denotes a ratio (%) of D-type (lactic acid monomer equivalent)) in the constituent unit where CH3—C*—H(—OH)(COOH) is dehydration condensed.

    摘要： A toner including a colorant and a binder resin is provided. The binder resin includes a first resin comprising a block X comprising a resin comprising a racemic mixture of optically active monomers of a D-form compound and an L-form compound, and a block Y comprising another resin. The weight ratio of the D-form compound to the L-form compound is from 48/52 to 52/48, and the weight ratio of the block Y to the block X is from 1/3 to 3/1. The toner is obtained by dispersing or emulsifying a toner constituent liquid, in which the colorant and the binder resin are dissolved or dispersed in an organic solvent, in an aqueous medium.
