Abstract:
A toner for developing an electrostatic latent image that includes a crystalline polyester resin and a release agent, wherein structures in which the crystalline polyester resin contacts the release agent exist in a ruthenium-stained cross section of the toner, and if the cross-sectional area of these structures is labeled A, the cross-sectional area of lone portions of the release agent is labeled B, and the cross-sectional area of lone portions of the crystalline polyester resin is labeled C, then 40≦100×A/(A+B+C)≦70, 10≦100×B/(A+B+C)≦30, and 20≦100×C/(A+B+C)≦30.
