Photosensitive body

Abstract

Abstract PURPOSE:To eliminate optical fatigue, and to improve photosensitivity characteristics, electrostatic charge retentivity characteristics, surface hardness, and durability by laminating on a conductive substrate a photoconductive layer contg. a-Si, and a light transmitting insulating overcoat layer contg. a-Si:C:O:F. CONSTITUTION:A photosensitive body is formed by laminating on a conductive substrate 1, a photoconductive layer 2 made of a-Si, and a light transmitting insulating overcoat layer 3 made of a-Si:C:O:F. The layer 3 contains 5-60atm% C and up to about 10atm% O, and up to about 10atm% F in a distribution uniform in the direction in parallel to the layer surface, and increasing in the film thickness direction. The photosensitive body having a photosensitive layer thus formed can form a sharp image of high density, excellent in resolution, and good in reproducibility of gradation, and it can obtain a good copy during successive copying without deteriorating image characteristics at all, and electrophotographic characteristics and image characteristics are not deteriorated and retained good even under high temp. and high humidity.
