<p>PROBLEM TO BE SOLVED: To prevent the first and second image forming positions on a sheet material from being deviated in a direction perpendicular to the sheet material conveying direction caused by the difference between sheet material conveying paths of a double-side mode and a multiplex mode by preventing jamming by easily housing the sheet material to a paper refeeding sheet material position regulating means regardless of the positional deviation in the direction perpendicular to the conveying direction in a sheet material conveying process, in an image forming device having a sheet material re-housing means. SOLUTION: An image forming device is provided with a paper refeeding sheet material position regulation means 312 positioned in a sheet material re-housing means 31 and for regulating the position perpendicular to the sheet material conveying direction, means 316 to 322 for moving the position of the means in the direction perpendicular to the sheet material conveying direction, a sheet material position detecting means PH1 for detecting the position perpendicular to the conveying direction of the sheet material to be fed to the sheet material re-housing means, and a control means for controlling the moving means according to the position of the detected sheet material and for changing the position of the paper refeeding sheet material position regulating means.</p> |
