PURPOSE: To obtain a photoreceptor always stable and superior in durability by laminating on a substrate the first layer made of an amorphous photo conductive material composed of silicon as a matrix and the second layer made of an amorphous material composed of silicon matrix contg. C.

CONSTITUTION: The photoreceptor 100 sensitive to electromagnetic waves, such as light, is composed of the substrate 101, the first layer 102 made of an amorphous photoconductive material composed of silicon as a matrix, sometimes contg. a conductivity governing substance, formed on the substrate 101, and the second layer 103 made of an amorphous material composed of silicon matrix contg. C and the conductivity governing substance, laminated on the first layer 102. The first layer 102 contains Ge in a uniform distribution in its partial layer region in contact with the substrate 101 and one of the first layer 102 and the second layer 103 contains oxygen in a uniform distribution in the whole or partial layer region.
