Electrophotographic photoreceptor

An electrophotographic photoreceptor comprising a conductive support and provided thereon a photoreceptive layer comprising a charge generation material and a charge transport material in admixture or a photoreceptive layer comprising a charge generation layer as a lower layer and a charge transport layer containing a charge transport material as an upper layer, said charge transport material being a compound represented by the following Formula 1:

• ##STR448## wherein X represents a group capable of forming a hydrogen bond;
• and R.sub.1, R.sub.2 and R.sub.3 are independently selected from the group consisting of a hydrogen atom, a halogen atom, an alkyl group, an aralkyl group, an alkoxy group, an aryl group, an aryloxy group, a heterocyclic group, a hydroxy group, a nitro group, a cyano group, an acyl group, a urethane group, a carboxyl group, a carboxylate ester group, an amido group, --NH.sub.2, --NHR and --NHCOR, in which R represents alkyl or aryl;
• and R' and R" are independently selected from the group consisting of a hydrogen atom, an alkyl group and an aryl group or R' and R" combine with each other to form a ring.
