    • The electrophotographic recording element comprises a charge generator compound formed from aniline sulphonephthelein derivatives, in which at least one phenyl ring comprises an amino group substituted by an aromatic or heterocyclic group. The recording element may consist of an electrically conducting support on which a layer is deposited containing the charge generator compound dispersed in a resin, then covered in its turn by a further electric charge transporter layer containing an oxadiazole derivative in solid solution in a resin. The recording element has high sensitivity to luminous radiation over a range extending from visible radiation to infrared, and can consequently be used in normal copying machines and especially in laser printers operating with a wavelength up to about 850 nm. According to a further version of the invention, the recording element comprises an electroconducting layer on which a single layer is deposited formed from a mixture prepared from a dispersion of an aniline sulphonephthalein derivative in a resin, and a solid solution of oxadiazole derivative.
