ABSTRACT:
A photosensitive member for electrophotography has a conductive substrate provided thereon with, in order, a charge transport layer, a charge generation layer, an interference control layer and an overcoating layer. The interference control layer has a refractive index substantially equal to the geometrical mean of the refractive indexes of the charge generation layer and the overcoating layer and a thickness such that the optical phase difference is substantially equal to .pi./2 radian or 3.pi./2 radian.
