Abstract
Photosensitive materials which comprise, on a conductive support, a layer structure having at least one layer. The at least one film is made of a cured film of a dispersion of a photoconductor in a binder polymer which has recurring units of the following general formula ##STR1## wherein each m is individually from 0 to 4, but at least one m is not 0, X.sub.1 and X.sub.2 are bromine atoms and n is an integer. The photoconductor may be X-type metal-free phthalocyanine or .tau.-type metal-free phthalocyanine dispersed partially in a molecular state and partially in a particulate state. Alternatively, combinations of carrier generation and carrier transport agents may be used. The layer structure is either a single-layer structure or a double-layer structure.
