摘要： A family of photoreceptors for use in electrophotography are disclosed which contain a binary charge generation composition of oxytitanium phthalocyanine and copper phthalocyanine. The charge generation composition exhibits adjustable photosensitivity by adjusting a ratio between said oxytitanium phthalocyanine and said copper phthalocyanine. To optimize its performance, the charge generation composition is subject to an ammonia-modified complexation-mediated crystal transformation, and the resultant composition is characterized by Bragg diffraction angles (2.theta..+-.2.degree.) of 7.7, 9.4, 10.7, 13.3, 15.2, 15.7, 26.3, 27.4, and 28.4 degrees with respect to the CuK.alpha. characteristic X-ray wavelength at 1.54 .ANG. and absorption maxima centered around 615, 690, and 770 nm in the optical absorption spectrum. The photosensitivity of the charge generation composition can be modulated according to the formula of ##EQU1## where i denotes each component in the charge generation mixture, X is the molar fraction V.sub.ddp is the dark development potential and E.sub.1/2 is the half decay energy.
