PROBLEM TO BE SOLVED: To provide a both-side image forming device which has the same productivity for both-face recording per recording material as that for one-face recording and is capable of suppressing the positional deviations of the front- and rear-side images of the recording material (the positional deviations of the top ends of the images, a magnification difference, a color shift at the time of recording a full color image, etc.), as little as possible. SOLUTION: The both-side image forming device for forming the images on the front and rear surfaces of the recording material 3 by two image forming parts A and B respectively is provided with an image position adjusting means 4 for making the positions of the front- and rear-side images T1 and T2 formed on the front and rear surfaces of the recording material 3 by the respective image forming parts A and B coincident with each other. |
