摘要： PURPOSE:To retain stably the high electrostatic charge potential of a photosensitive body and to provide satisfactory optical fatigue characteristics and suitability to negative electrostatic charge by incorporating a specified amount of O into the charge transferring layer of hydrogenated and/or fluorinated a-SiC formed under the charge generating layer of hydrogenated and/or fluorinated a-Si. CONSTITUTION:A charge transferring layer 42 of amorphous hydrogenated and/ or fluorinated silicon carbide is formed under a charge generating layer 43 of amorphous hydrogenated and/or fluorinated silicon, and 50-500ppm O (Si+C= 100atom%) is incorporated into the layer 42 to obtain a separated function type photosensitive body. By incorporating 50-500ppm O into the layer 42, the charge retentivity (dark resistance) is effectively increased without reducing the charge transferring power, and the temp. dependency of the dark resistance can be controlled. Accordingly, it is necessary to set the O content at 50-500ppm, desirably 70-300ppm. The electrostatic charge potential retentivity is increased, the upper limits of the service temp. and humidity of the photosensitive body can be increased, and the photosensitive body is made suitable for negative electrostatic charge.
