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. oxygen and halogen atoms and an electric charge generating layer of a hydrogenated or fluorinated amorphous silicon film contg. 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 oxygen and halogen atoms and the charge generating layer 3 is formed of the hydrogenated or fluorinated amorphous silicon a-Si film which contains either of the phosphorus atoms or boron atoms. The content of the oxygen in the a-C film is specified to <=7% of the total constituting atoms, the content of the halogen to 0.1-25% and the content of the phosphorus or boron in the a-Si film is specified to <=20,000ppm. The charge transfer layer 2 is thereby improved in transferability, electric chargeability, durable weatherability 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. |
