    摘要: An electrophotographic recording material contains, as charge carrier-transporting compounds in the photoconductor layer, a mixture of one or more compounds of the formula ##STR1## and one or more compounds of the formula ##STR2## in a ratio of from 9:1 to 0.6:1, preferably from 2.3:1 to 0.8:1. In the formulae, R.sup.1 and R.sup.2 independently of one another are each alkyl, allyl, phenylalkyl or unsubstituted or substituted phenyl, R.sup.3 and R.sup.4 independently of one another are each hydrogen, alkyl, alkoxy or halogen, and R.sup.6, R.sup.7, R.sup.8 and R.sup.9 independently of one another are each alkyl, phenylalkyl or cyclohexyl.When the mixture of (I) and (II) is present in an appropriate concentration, the recording materials are highly photosensitive, although the problems usually encounted in the case of high concentrations of charge carrier-transporting compounds do not arise.
