Abstract
To provide an electrophotographic toner, which contains a crystalline resin, a non-crystalline resin, a colorant, and a releasing agent, wherein the toner has a storage elastic modulus of 5.0×10Pa to 5.0×10Pa at 80° C., and a storage elastic modulus of 2.0×10Pa to 2.0×10Pa at 140° C., and wherein the toner has a ratio (C)/((C)+(A)) of 0.10 or greater, where (C) is an integrated intensity of a diffraction spectrum derived from a crystalline structure, (A) is an integrated intensity of a diffraction spectrum derived from a non-crystalline structure, and the diffraction spectrum is a diffraction spectrum of the toner as measured by an X-ray diffraction spectrometer.
