Abstract
An electrostatic latent image developing toner includes a plurality of toner particles containing a binder resin. The toner particles have a cross-linking structure originating from a high-molecular cross-linking agent. A storage elastic modulus of the toner at a temperature of 80° C. is at least 1.0×10Pa and no greater than 5.0×10Pa. A storage elastic modulus of the toner at a temperature of 120° C. is at least 1.0×10Pa and no greater than 1.0×10Pa. A cross-linking density Nx represented by formula (1) is at least 2.9×10mol/cmand no greater than 2.5×10mol/cm. A loss tangent tan δx represented by formula (2) is at least 0.05 and no greater than 0.50.=10××(+343)  (1)tan δ  (2)
