Appeal No. 98-0140
S.N. 08/401761
3. An electrophotographic photoconductive material
comprising a titanyl phthalocyanine crystal having a
primary particle diameter ranging from 0.03 to 0.15 µm,
showing a maximum X-ray diffraction peak at a Bragg
angle of (2T+0.2°) of 27.3°, having a ellipsoidal
tabular form, and having a BET specific surface area of
not less than 35 m2/g.
