Abstract
A photoconductive member for electrophotography wherein an electric field is established across a light amplification layer comprising a first transparent electrode, a field-effect light-emitting layer, a second photoconductive layer and a second electrode after the first photoconductive layer has been uniformly charged when a light image impinges on the first photoconductive layer, the portion of the field-effect light-emitting layer corresponding to the light image emits light to the first photoconductive layer, whereby an electrostatic image is formed on the first photoconductive layer by both the light image impinged thereon and the light emitted from the field-effect light-emitting layer.
