This invention relates to an improvement in an electrophotographic recording material comprising an electrically conductive support, optionally an insulating intermediate layer, and a photoconductive layer composed of at least one layer comprising charge carrier-producing and charge transporting compounds, a binder, and conventional additives, the improvement that the recording material comprises a 75 to 250 mu m thick support and, in the form of a photoconductor web, is sufficiently flexible that it is not prone to the formation of hairline cracks when repeatedly conducted over rollers of at least 18 mm diameter, said binder being a cellulose acyl ester with an acetyl content of not more than 30 percent and a viscosity of more than 15 poises, measured by the ASTM methods D 817-65, Formula A, and D 1343-56. |
