Abstract
A method for forming an electrophotographic imaging member comprising electrochemically depositing amorphous selenium on a conductive substrate while simultaneously illuminating the substrate with electromagnetic radiation through a periodic spatial light modulating means. The deposited selenium layer has a periodically varying thickness. The selenium layer is then overcoated with a layer of a charge carrier transport material which is capable of transporting at least one species of charge carrier. The resulting imaging member has extended range and solid area reproduction capability.
