<p>PURPOSE:To obtain the image of high definition by inclining the panel surface of a liquid crystal shutter array to the optical path for exposure and disposing it. CONSTITUTION:The surface of a photosensitive drum 2 is previously and uniformly electrified by an electrifier 5 and the surface of the photosensitive drum 2 is irradiated with a luminous signal generated from a printer head part 10 consisting of a fluorescent lamp 3 and the liquid crystal shutter array 1, so that an electrostatic latent image in accordance with an information signal is formed. Now, the panel surface 13 of the liquid crystal shutter array 1 is inclined to the optical path for exposure 12 from the fluorescent lamp 3 to the photosensitive drum 2 to be disposed. Thus, the opening and closing efficiency (contrast) of the liquid crystal shutter array 1 can be improved and the photosensitive drum 2 can be irradiated with the luminous signal having sufficient S/N, thereby obtaining the favorable image.</p> |
