Zusammenfassung:An electrostatic charge image developing toner includes toner particles that contain a polyester resin which includes a condensed polymer of a polyvalent carboxylic acid and a polyol which contains ethylene glycol in an amount of from about 40% by weight to about 90% by weight with respect to a total amount of the polyol, and an external additive that contains silica particles in which a product of a volume average particle diameter D50 (μm) and a BET specific surface area SA (m2/g) is from about 1.4×103 to about 5.0×103.
