Abstract
An electrostatic latent image developing toner includes a plurality of toner particles containing a binder resin. The binder resin has an amide bond and an ester bond. An area ratio of a peak originated from C═O stretching of the amide bond to a peak originated from C═O stretching of the ester bond is at least 0.00010 and no greater than 0.02000 in a FT-IR spectrum of the toner obtained by Fourier transform infrared spectroscopy analysis. The toner has a storage elastic modulus at 80° C. of at least 3.5×10Pa and no greater than 5.0×10Pa. The toner has a storage elastic modulus at 120° C. of at least 1.0×10Pa and no greater than 10×10Pa. The toner has a storage elastic modulus at 150° C. of at least 1.0×10Pa and no greater than 10×10Pa.
