PROBLEM TO BE SOLVED: To provide an image forming device capable of making the writing references of images on a first face coinside with a second face in writing the images on both faces of the sheet. SOLUTION: Sensors 35a, 35b are mounted in adjacent to a recording paper delivering passage to measure a length in the delivering direction of the recording paper 50, and an image transfer position to the recording paper 50 is controlled, to align a center of the image on the first face and that of the second face of the recording paper 50. The disagreement in the image sizes of the firs face and the second face of the recording paper can be prevented by controlling a image transfer size to the recording paper. |
