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 CH.sub.3--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 CH.sub.3--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 CH.sub.3--C*--H(--OH)(COOH) is dehydration condensed.
