PROBLEM TO BE SOLVED: To feed transfer paper whose inclination and biasing are corrected in a double-sided image forming device where a transfer paper set reference position is in the center of an optical axis and an image for a second side is formed after an image for a first side is formed on the transfer paper. SOLUTION: A temporary stop roller 52 is provided in a reversal paper feeding path for feeding the paper for the second side on the upstream side of a resist roller 44 common to the first side and the second side for feeding the transfer paper to an image forming part at a specified time, and a transfer paper reference position sensor S1 capable of moving in a paper width direction is provided on the more upstream side, and a pair of rollers 51C is provided on the more upstream side. By turning on a copying start button, the sensor S1 is moved to a position in accordance with the size of the transfer paper, and the transfer paper fed through the reversal paper feeding path forms a loop between the roller 52 stopped temporarily and the pair of rollers 51C and is fed by the roller 52 rotating while moving in a perpendicular direction to a paper passing direction based on information from the sensor S1. |
