Abstract:
A photoreceptor for use in electrophotography containing a binary charge generation composition of oxytitanium phthalocyanine and copper phthalocyanine which exhibits adjustable photosensitivity by adjusting a ratio between said oxytitanium phthalocyanine and said copper phthalocyanine; wherein said binary charge generation composition of oxytitanium phthalocyanine and copper phthalocyanine has been subject to an ammonia-modified complexation-mediated crystal transformation so as to exhibit a linearly additive photosensitivity as described by the following formula: ##EQU4## where i denotes each component in the charge generation composition, X is the molar fraction V.sub.ddp is the dark development potential and E.sub.1/2 is the half decay energy.
