Multi-active photoconductive insulating elements which are sensitive in the far red region of the spectrum are comprised of a charge-generation layer and a charge-transport layer in electrical contact therewith and contain, as the charge-generating agent within the charge-generation layer, the compound N,N'-bis[2-(3-methylphenyl)ethyl]perylene-3,4:9,10-bis(dicarboximide). The charge-generation layer is capable, upon exposure to activating radiation, of highly effective generation and injection of charge carriers and the charge-transport layer, which is comprised of an organic composition containing an organic photoconductive material, is capable of accepting and transporting the injected charge carriers to thereby form a highly advantageous multi-active photoconductive insulating element.
