Abstract (en)

[origin: US4220697A] 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 12 mm diameter, said binder being a cellulose nitrate with a viscosity of 400+/-25 cPoises at concentrations between about 4 and 12 percent in a 5 percent aqueous acetone solution, according to DIN 53 179 (standard type 4-12).
