ABSTRACT:
A multiactive photoconductive element exhibiting reduced black spots in discharged area development systems. The element includes (A) a conductive layer, (B) an aggregate charge generation layer in direct physcial contact with the conductive layer and (C) a charge transport layer. The charge generation layer contains (i) a binder an adhesive polymer. The charge transport layer contains a binder according to formula II: ##STR1## wherein the Ar, R.sup.1, R.sup.2, R.sup.7, R.sup.8, R.sup.3, R.sup.4, R.sup.5, R.sup.6, R.sup.9, R.sup.10, R.sup.11, and R.sup.12 and x are defined in the specification.
