Abstract

PURPOSE: To form the title member not polluting environment, having superior resistance to heat, humidity, and all kinds of adverse environments, and stabilized electrophotographic characteristics, by using a photoconductive layer made of an amorphous Si type, and by providing a depletion layer in this layer.
CONSTITUTION: Internal layer 6 made of an i-type a-Si layer is vapor deposited on conductive substrate 2, and external layer made of a p type a-Si layer 7 is vapor depositied on layer 6. When the junction of different types of a-Si layers is thus made and a photoconductive layer 3 having free surface 4 is formed, depletion layer 5 is formed in the boundary transient region between layers 6 and 7. In an electromagnetic wave irradiation step in an electrostatic latent image forming process, layer 5 has a fuction as a layer absorbing the electromagnetic wave and generating movable carriers. This permits electrophotographic image forming member 1 superior in light fatigue resistance and corona ion resistance and not causing deterioration phenomenon even in repeated uses to be obtained.
