Abstract
The present toner is an electrostatic latent image developing toner, and contains a toner base particle. The toner base particle contains a binder resin and a release agent. The binder resin contains a crystalline resin and a vinyl resin. When the storage elastic modulus G′ at 50° C. is defined as G′50° C., the peak top temperature (° C.) of a specific endothermic peak in DSC of the toner is defined as Tm, the measurement temperature (° C.) at a G′ of 1×106 Pa is defined as TmA, and the measurement temperature (° C.) at a G′ of 1×105 Pa is defined as TmB, the toner satisfies the following expressions (1) to (3):G′50° C.≧1×108 (1)TmB−TmA≦8 (2)Tm<TmB (3).
