Abstract

See full text

An imaging member includes a charge generating layer and a charge transport layer. The charge transport layer includes a first surface in contact with the charge generating layer and a second surface. The charge transport layer includes a film forming polymer binder and a charge transport component dispersed therein. The concentration of the charge transport component in the charge transport layer is at a peak in a region of the charge transport intermediate the first and second surfaces of the charge transport layer.
