Abstract
A photoconductor for electrophotography includes a photoconductive layer that contains titanyloxyphthalocyanine as a charge generation agent. The concentration of SO.sub.4.sup.2- with respect to the concentration of titanyloxyphthalocyanine is adjusted to be less than or equal to 500 ppm. The photoconductor may be of either a monolayer or a laminate construction. In the case of a laminate type photoconductor, the titanyloxyphthalocyanine is incorporated into the charge generation layer.
