Abstract
An electrophotographic sensitive material is described having an electrophotographic sensitive layer containing a charge generating material and a charge transfer material, wherein said charge generating material comprises a barbituric acid derivative or thiobarbituric acid derivative represented by formula (I) or (II) ##STR1## wherein (i) X represents an oxygen atom or a sulfur atom PA1 (ii) R.sup.1 represents an alkoxy group, an aralkyl group or a substituted amino group represented by ##STR2## wherein R.sup.7 and R.sup.8 each represents an unsubstituted or substituted alkyl group or phenyl group, or R.sup.7 and R.sup.8 together represent a group forming a nitrogen atom-containing heterocyclic ring, PA1 (iii) R.sup.2 and R.sup.3 each represents a hydrogen atom, a halogen atom, an alkyl group, or a lower alkoxy group, PA1 (iv) R.sup.4 represents a hydrogen atom, an alkyl group, or an unsubstituted or substituted phenyl group, PA1 (v) R.sup.5 and R.sup.6 each represents an alkyl group, an aralkyl group, or an unsubstituted or substituted phenyl group, and PA1 (v) R.sup.5 and R.sup.6 each represents an alkyl group, an aralkyl group, or an unsubstituted or substituted phenyl group, a…
