An electrophotographic image forming apparatus comprising:
- an electrophotographic photoreceptor comprising:
- an electroconductive substrate;
- a charge generation layer; and
- a charge transport layer in this order,
- a charger;
- an irradiator;
- an image developer; and
- a transferer applying an electric current not less than 65 A
to the electrophotographic photoreceptor,
- wherein the charge generation layer comprises titanylphthalocyanine
crystals having a CuK 1.542 X-ray diffraction spectrum having plural
diffraction peaks, wherein a maximum diffraction peak is observed at a Bragg (2
) 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.
