<p>PROBLEM TO BE SOLVED: To form highly resolution dot lines in a row with respect to the axial direction of a photosensitive body drum by allowing an LED array head to shift slantingly relative to the axial direction of the photosensitive body drum in use of an oscillation device, and making the LED array head give off light in its before and after period while keeping the rotation speed of the photosensitive drum constant. SOLUTION: The LED array head 16 is provided with an oscillation device 44, and this is driven by a driver 46. Thus, the LED array head is shifted at a predetermined degree in the direction of an angle ofθwith respect to the axial direction of the photosensitive body drum. Then, in the before and after period of the shift, a light-emitting diode units light in accordance with each video data so as to write static latent images according to the video data in the photosensitive body drum.</p> |
