Electrophotographic photoreceptor

摘要

Disclosed is an electrophotographic photoreceptor contains a carrier generation material represented by Formula 1 or 2 having peaks at 2 theta =6.3 DEG , 12.4 DEG , 25.3 DEG and 27.1 DEG in the Bragg angle (2 theta +/-0.2 DEG ) as measured by X-ray diffraction under radiation of Cu-K alpha rays; said peak of 12.4 DEG has a maximum intensity and has a half width of 0.65 DEG or more; no peak being present at 11.5 DEG ; and a carrier transportation material selected from the group consisting of the following Formulas 3, 4, 5 and 6; Formula 1:esents an atomic group necessary to form a substituted or unsubstituted heterocyclic ring; Formula 3: <IMAGE> Formula 4: <IMAGE> Formula 5: <IMAGE> Formula 6: <IMAGE>
