ABSTRACT:
High speed organic photoconductors are produced by crystallizing p-terphenyl from solution in a solvent having defined solubility parameter limits. Heterogeneous photoconductive insulating compositions comprising a dispersion of these p-terphenyls in an electrically insulating binder can be applied to an electrically conducting support to provide an electrophotographic element with high photoconductive speed.
