An electrostatic-image developing toner contains toner particles containing a polyester resin having an acid value of from 10 mg KOH/g to less than 15 mg KOH/g. The toner particles have a surface with an acid value in a range from 0.3% to 1.7% of the acid value of the polyester resin. The toner particles have a melt viscosity of from 1,800 Pa&#xb7;s to 3,800 Pa&#xb7;s at 100&#xb0; C.

Electrostatic-image developing toner, electrostatic image developer, and toner cartridge

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&#x2266;100&#xd7;A/(A+B+C)&#x2266;70, 10&#x2266;100&#xd7;B/(A+B+C)&#x2266;30, and 20&#x2266;100&#xd7;C/(A+B+C)&#x2266;30.
