PURPOSE:To obtain a photoconductive material having always stable electrical, optical, and photoconductive characteristics almost unaffected by use environments, markedly excellent optical fatigue resistance, these characteristics not deteriorated by repeated uses, superior durability, and residual potential observed not at all or very little. CONSTITUTION:A photoconductive material 100 comprises a substrate 101, a first photoconductive amorphous layer 102 composed of amorphous material contg. Si as an essential constituent, and hydrogen H and/or halogen X: a-Si (H, X), and a second amorphous layer 106 composed of Si, C, and halogen. The layer 102 has a first layer region 103 contg. O as a constituent, and a second layer region 104 contg. an element of group III of the periodic table in a distribution state continuous in the thickness direction and rich on the side of the substrate 101, and the region 103 is located on the side of the substrate in the layer 102. |
