PROBLEM TO BE SOLVED: To provide an electronic photograph-type printing device where an error does not occur in the printing length in the auxiliary scanning direction even if a slip has occurred between printing paper and a photoreceptor drum. SOLUTION: The surface of a photoreceptor drum 11 is electrified by a charging part 12. Picture data in the main scanning direction of input picture data being the object of printing are sequentially taken into an exposure part 13 in the auxiliary scanning direction every one line. Data for one line are exposed by the photosensitive drum 11 at a period T and an electrostatic latent image is formed. Toner is adhered to the electrostatic latent image by a developing part 14 and it is made into a visible image. Printing paper P is supplied from a cut paper feeding part 21 and it is transported to a transfer part 15. The transfer part 15 transfers the visible image of the photoreceptor drum 11 to printing paper P. The image transferred to the printing paper P is fixed by a fixing part 18. When printing paper P is supplied from a roll paper feeding part 22 or a roll paper feeding part 23, a slip occurs between printing paper P and the photoreceptor drum 11. Thus, the period T is adjusted based on the slip. |
