ABSTRACT:
An electrophotographic image forming apparatus comprising:an electrophotographic photoreceptor comprising:an electroconductive substrate;a charge generation layer; anda charge transport layer in this order,a charger;an irradiator;an image developer; anda transferer applying an electric current not less than 65 μA to the electrophotographic photoreceptor,wherein the charge generation layer comprises titanylphthalocyanine crystals having a CuKα 1.542 Å X-ray diffraction spectrum having plural diffraction peaks, wherein a maximum diffraction peak is observed at a Bragg (2θ) angle of 27.2°; main peaks are observed at 9.4°, 9.6° and 24.0°; and a minimum diffraction peak is observed at 7.3°; and no diffraction peak is observed at an angle greater than 7.3° and less than 9.4°, wherein said angles may vary by ±0.2° and the minimum interval where no peak is observed between required peaks at 7.3 and 9.4 is 2.0 degrees absolute or more.
