Abstract
A photosensitive material for electrophotography, wherein the charge-generating agent comprises a P-type charge-generating pigment and an N-type charge-generating pigment in combination, at least part of these pigments being present in the form of aggregates in the photosensitive layer. The photosensitive material will assume the form of either a single dispersion type or a laminated layer type, and exhibits very high carrier generation efficiency, strikingly improved sensitivity on the side of long wavelengths, excellent balance in the spectral sensitivity and property after repetitively used, and can hence be effectively used for forming image by the electrophotography.
