Abstract
The present invention provides an multilayer type electrophotographic element comprising laminating a charge generating layer containing a trisazo pigment represented by the general formula (1) on an electrically conductive substrate: ##STR1## (wherein, R denotes ##STR2## and laminating a charge transfer layer containing an .alpha.-substituted stilbene compound represented by the general formula (2): ##STR3## (wherein, R.sup.1 denotes a substituted or unsubstituted alkyl group or a substituted or unsubstituted aryl group, R.sup.2, R.sup.3, and R.sup.4 each denotes a substituted or unsubstituted alkyl group or a substituted or unsubstituted aryl group, and Ar.sup.2 denotes a substituted or unsubstituted arylene group. Ar.sup.1 and R.sup.1 may be combined to form a ring. n is an integer of 0 or 1) and a resinous binder, on the charge generating layer.
