Provided is an electrostatic image developing toner comprising a toner base particle containing a binder resin and a releasing agent, wherein the binder resin comprises an amorphous vinyl resin and a crystalline polyester resin; a weight-average molecular weight of the electrostatic image developing toner is in the range of 50000 to 90000, when calculated from a chromatogram which represents a molecular weight distribution and is measured by gel permeation chromatography; a ratio of content of a resin component having a molecular weight of 100000 or more is in the range of 10 to 20% by area, in the chromatogram which represents the molecular weight distribution; the crystalline polyester resin has a melting point in the range of 65 to 85° C.; and, a ratio of content of the crystalline polyester resin in the binder resin is in the range of 5 to 20% by mass.
