Abstract
An electrophotographic element has a surface layer with a ratio of the number of nitrogen atoms to silicon atoms of 0.5 or more, and a reflection factor is the surface layer for coherent light beams of 0.1 or less. Use of such an element prevents excessive light reflection at the surface layer, thereby preventing reflected light beams from forming interference fringes in a printed image. In this respect, the electrophotographic element according to the present invention is suitable for use as a photosensitive element in a laser printer utilizing a semiconductor laser beam as its light source.
