PROBLEM TO BE SOLVED: To stabilize a state of a alignment mark pictured on a dielectric belt, and to perform the highly precise alignment by setting potential of the dielectric belt to a value suitable to the alignment. SOLUTION: In this image forming device, voltage changing means 50 on starting, instruct power feeding means 70 so as to apply the voltage different from the normal printing time corresponding to a destaticizing brush and an electrification roller, the same voltage as the normal printing time to a photoreceptor drum and the transfer roller. In this way, when the voltage is applied by the power feeding means 70, image formation controlling means 20 is started, and the alignment mark stored in a video ROM 21 is formed on the dielectric belt 12. Next, aligning means 40 start, and the aligning process is performed by comparing the alignment mark obtained from a CCD sensor 30 with a reference condition. On completing the aligning process, the aligning means 40 lower the CCD flag, and the voltage changing means 50 instruct the power feeding means 70 so as to apply the voltage of normal printing time. |
