<p>PROBLEM TO BE SOLVED: To provide a colored image-forming apparatus which can form higher quality full color prints while relatively moving a photosensitive paper at a constant speed to an optical shutter array. SOLUTION: The light from an exposure light source 9 passes sequentially from a red, a green and a blue filters and enters a liquid crystal shutter array 11. The liquid crystal shutter array has a plurality of orthogonal pixel arrays to a move direction of the photosensitive paper and operates as follows. Specifically, the liquid crystal shutter array opens/closes pixels of each array in accordance with image data for each of the color lights from the exposure light source thereby exposing the photoreceptor for each line. At this time, pixels of pixel arrays not selected to be an exposure region of the exposed line are kept in a close state. Three pixel arrays to be selected are shifted one by one every time the color light is changed over. Colored images are optically written on the photosensitive paper in this manner.</p> |
