Abstract: A toner for developing electrostatic images includes at least a binder resin and a colorant containing a copper phthalocyanine compound, wherein in X-ray diffraction using a CuKα ray, the toner has peaks at a Bragg angle of 2θ=7.0±0.1° and at a Bragg angle of 2θ=9.1±0.2° and additionally has a peak between the two peaks.
