<p>An optical printer has an optical head (100) which has a built-in LED light source (110) is moved relatively to a photosensitive paper (500) and allows the light source to emit a plurality of color lights from LEDs at predetermined time intervals so as to project the lights on the photosensitive paper at predetermined intervals. The image pitches P of the color lights are approximately equal to an integral multiple of the maximum exposure distance D.</p> |
