An electrostatic charge image developing toner includes a binder resin and a release agent. A ratio of a crystalline polyester resin to the total amount of a amorphous polyester resin and the crystalline polyester resin is within a range exceeding 40% by mass to 60% by mass. A temperature at which a storage modulus before heat left G′ before being left to stand at a temperature of X° C. becomes 1.0×108 Pa is within a range exceeding 45° C. to 55° C. A storage modulus after heat left G′ at a temperature of X′° C. at which a value of a ratio of the storage modulus after heat left G′ at a temperature of X° C. after being left to stand at the temperature of X° C. for 2 hours to the storage modulus before heat left G′ at the temperature of X° C. becomes the maximum is within a range of 1.0×108 to 5.0×108 Pa.
