ABSTRACT:
Disclosed is a charge transfer material which is highly soluble in a binder resin, does not precipitates crystals and produces no pinhole and also disclosed is an electrophotographic photoreceptor comprising the charge transfer material which comprises a butadiene compound represented by the formula (I): ##STR1## wherein R.sup.1 and R.sup.2, which may be the same or different, respectively represent a lower alkyl group having 1-4 carbon atoms or a phenyl group or benzyl group which may have a substituent and R.sup.3, R.sup.4 and R.sup.5, which may be the same or different, respectively represent a hydrogen atom, a halogen atom, a lower alkyl group, a lower alkoxy group having 1-4 carbon atoms or a halogen atom; and a butadiene compound represented by the general formula (II): ##STR2## wherein R.sup.1, R.sup.2, R.sup.3, R.sup.4 and R.sup.5 are the same as above, and the content of the butadiene compound of the formula (I) is at least 60% by weight based on the total amount by weight of the butadiene compounds of the formulae (I) and (II).
