A toner includes a binder resin and a colorant. The binder resin contains a polyester resin A obtained by subjecting aromatic dicarboxylic acid, rosin, and trivalent or higher-valent alcohol as starting materials to polycondensation, a content of the rosin in a sum of the starting materials being 60% by weight or more, and a polyester resin B obtained by subjecting aromatic dicarboxylic acid and polyhydric alcohol as starting materials to polycondensation, the polyester resin B having a viscosity of 103 Pa·s or more and 105 Pa·s or less at a softening temperature of the polyester resin A, the polyester resin B being contained in an amount of 50 parts by weight or more and 200 parts by weight or less relative to 100 parts by weight of the polyester resin A.
