Electrophotographic recording material

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 by weight in a 5 percent aqueous acetone solution, according to DIN 53 179 (standard type 4-12), the proportion of cellulose nitrate to charge transporting compound being in the range of about 20 to 60 parts by weight to 40 to 80 parts by weight.
