<p>PROBLEM TO BE SOLVED: To eliminate main scanning or the like operation as a light source in an internal image exposure system, and remarkably improve registration of colors. SOLUTION: The digital printer has an EL pixel array 134 attached to an entire circumferential face of a photosensitive drum, thereby constituting an internal light source. Pixels controllable by a TFT layer 144 are allotted to the whole of an image formation area of the photosensitive drum. A mechanism for moving the light source in a main scanning direction as in a conventional internal light source using an LED is eliminated, and factors causing a deviation of image positions of colors are totally eliminated. Full color images of a high- quality can be obtained without a color shift or the like at all.</p> |
