Abstract
An electrophotosensitive member for use in electrophotography includes a plurality of amorphous silicon and amorphous silicon:germanium layers that are arranged in an alternating fashion. The two outermost layers are made up of amorphous silicon so that each amorphous silicon:germanium layer is sandwiched between two amorphous silicon layers.
