The present invention is a photoconductive element that includes an electrically conductive support, an electrical barrier layer disposed over said electrically conductive support, and disposed over said barrier layer, a charge generation layer capable of generating positive charge carriers when exposed to actinic radiation. The barrier layer includes a vinyl polymer with aromatic tetracarbonylbisimide side groups and crosslinking sites.
