ABSTRACT:
A novel titanyl phthalocyanine crystal, a photoconductive material comprising the same, and an electrophotographic photoreceptor using the same are disclosed. The titanyl phthalocyanine crystal has a primary particle diameter ranging from 0.03 to 0.15 .mu.m, shows a maximum X-ray diffraction peak at a Bragg angle (2.theta..+-.0.2.degree.) of 27.3.degree., has a ellipsoidal tabular form, and has a BET specific surface area of not less than 35 m.sup.2 /g. The crystal has improved crystal form stability against solvents and holds its crystal form for an extended period of time in a dispersed and coated state. An electrophotographic photoreceptor using the crystal as a photoconductive material is excellent in sensitivity, stability, and durability.
