Patent ID: 10289015

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 1.0×103 Pa and no greater than 5.0×104 Pa. A storage elastic modulus of the toner at a temperature of 120° C. is at least 1.0×103 Pa and no greater than 1.0×104 Pa. A cross-linking density Nx represented by formula (1) is at least 2.9×10−7 mol/cm3 and no greater than 2.5×10−6 mol/cm3. A loss tangent tan δx represented by formula (2) is at least 0.05 and no greater than 0.50. Nx=10×Gx/R×(T10000+343)  (1)tan δx=Gy/Gx  (2)
