Abstract
Oxytitanium phthalocyanine having a crystal form characterized by main peaks specified by Bragg angles (2.sigma..+-.0.2 degree) of 9.0 degrees, 14.2 degrees, 23.9 degrees and 27.1 degrees in X-ray diffraction pattern based on CuK.alpha. characteristic X-rays. The oxytitanium phthalocyanine crystal provides an electrophotosensitive member showing a high and stable photosensitivity for long-wavelength light as well as a stable chargeability even after photoirradiation.
