ABSTRACT:
There is provided an improved light receiving member comprising a substrate and a light receiving layer formed by laminating a first layer having photoconductivity which is constituted with an amorphous material containing silicon atoms as the main constituent atoms and germanium atoms, and a second layer constituted with an amorphous material containing silicon atoms, carbon atoms and an element for controlling the conductivity. The germanium atoms contained in the first layer is in the state of being unevenly distributed in the entire layer region or in the partial layer region adjacent to the substrate. The first layer may contain one or more kinds selected from an element for controlling the conductivity, oxygen atoms and nitrogen atoms in the entire layer region or in the partial layer region.
