摘要： 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.

摘要： The Invention is an image input apparatus equipped with means of image shifting which is capable of inputting images of different resolutions, and enables the transmission band of the spatial filter to be switched in accordance with resolution in order to prevent moire. When a flat transparent refraction plate 22 is inclined relative to the optical axis 10 by which light from the object is introduced, the position where the image is formed on the imaging surface of the CCD 14 is shifted, thus making image shifting possible. High resolution images are obtained by shifting the image a distance shorter than the distance between the photosensitive parts of the CCD 14, and then combining the images. The transmission band of the spatial filter 12 for preventing moire can be switched by changing the relative angles of the double refraction plates 20, 21. The transmission band of the spatial filter 12 is switched to the high frequency side when inputting high resolution images by means of the image shift mechanism 13, thus obtaining images of good resolution.
