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.
Claims13
A photoconductor for electrophotography, comprising:
- a conductive substrate;
- a photoconductive layer;
- said photoconductive layer including titanyloxyphthalocyanine;
- and
- a concentration of SO.sub.4.sup.2- with respect to a concentration of said titanyloxyphthalocyanine in said photoconductive layer being from 100 ppm by weight to not more than 500 ppm by weight.
A method for manufacturing a photoconductor for electrophotography, comprising the steps of:
- producing a photoconductive material containing a titanyloxyphthalocyanine compound;
- adjusting an SO.sub.4.sup.2- concentration in said photoconductive material with respect to a concentration of said titanyloxyphthalocyanine compound to be from 100 ppm by weight to not more than 500 ppm by weight;
- and
- thereafter coating said photoconductive material onto a conductive substrate.
