Abstract:
An electrostatic latent image-developing toner includes a styrene-acrylic resin, an amorphous polyester resin, and a crystalline polyester resin. The electrostatic latent image-developing toner shows maximum absorption peaks at least in absorption wavenumber ranges of 690 to 710 cm−1, 1190 to 1220 cm−1, and 1230 to 1300 cm−1 in an absorption spectrum measured by attenuated total reflection with a Fourier transform infrared spectrometer. The ratio (P3/P1) of the height (P3) of the maximum absorption peak in the range of 1230 to 1300 cm−1 to the height (P1) of the maximum absorption peak in the range of 690 to 710 cm−1 is 0.02 to 6.00.
