Abstract
The invention provides a multiactive electrophotographic element comprising an electrically conductive substrate, a charge generation layer, and a charge transport layer, wherein the charge transport layer contains an electron transport agent having the structure: ##STR1## wherein J is H, Cl, Br, alkyl, alkoxy, aryl, or aryl further substituted with halo or alkyl; and wherein R is styryl, aryl, or heteroaryl in which the hetero atom is S or O, each of which R is unsubstituted or further substituted with alkyl, halo, alkoxy, nitro, hydroxy, cyano, trifluoromethyl, alkylsulfonyl, arylsulfonyl, alkoxycarbonyl, amino, alkylamino, dialkylamino, arylamino, or alkylarylamino. Such an element exhibits a good combination of electrophotographic performance properties.
