Abstract
An electrophotographic photoreceptor comprising a conductive substrate and a photosensitive layer on the conductive substrate, wherein the photosensitive layer contains a compound of formula (I) as a charge transporting agent: ##STR1## wherein R.sub.1 and R.sub.2 each represents a hydrogen atom, an alkyl group, an aryl group, an alkoxycarbonyl group, an aryloxycarbonyl group, a nitro group, a halogen atom, an alkylcarbonyl group or an arylcarbonyl group; Y represents ##STR2## X.sub.1 and X.sub.2 may be the same or different groups and are selected from a cyano group or an alkoxycarbonyl group; Z represents ##STR3## R.sub.3 represents a substituted or unsubstituted aryl or nitrogen-containing heterocyclic group; R.sub.4, R.sub.5 and R.sub.6 each represents a hydrogen atom, an alkyl group, an aralkyl group, an aryl group or a heterocyclic group; when Z is the ##STR4## group, R.sub.1 and R.sub.2 are not the alkylcarbonyl group; m is 0 or 1; n is 0 to 2; and when n is 2, the R.sub.1 groups may be the same or different.
