PURPOSE:To form a photosensitive layer which has excellent photosensitive characteristics and is extremely thin in film thickness by forming an electric charge transfer layer of a hydrogenated amorphous carbon film contg. nitrogen and halogen atoms and an electric charge generating layer of a hydrogenated or fluorinated amorphous silicon film contg. oxygen and at least either of phosphorus or boron atoms, respectively. CONSTITUTION:The charge transfer layer 2 of a function sepn. type photosensitive body having the charge transfer layer 2 and the charge generating layer 3 is formed of the hydrogenated amorphous carbon a-C film which is formed by glow discharge and contains the nitrogen atoms and halogen atoms and the charge generating layer 3 is formed of the hydrogenated or fluorinated amorphous silicon a-Si film which contains at least either of the phosphorus atoms or boron atoms and contains the oxygen atoms. The content of the nitrogen in the a-C film is specified to <=5% and the content of the halogens to 0.1-25%. The content of the oxygen in the a-Si film is specified to 0.001-1% and the content of the phosphorus or boron to <=20,000ppm. The charge transfer layer 2 is thereby improved in transferability, electric chargeability, durability and translucency, and the charge generating layer 3 is provided with the excellent photoconductivity of visible light and wavelength light near laser light and is extremely reduced in the film thickness. |
