<p><P>PROBLEM TO BE SOLVED: To provide a toner image deviation correcting device, configured to correct image deviation between toner images in both electrophotographic image forming apparatuses, when the electrophotographic image forming apparatuses are connected together. <P>SOLUTION: The correcting device includes: a first detection detecting 301, disposed on a conveyance upstream side with a transfer nip N as the base point and configured to detect the first toner image on a sheet material during conveyance; a retransfer roller 304 disposed on a conveyance downstream side with the transfer nip N as the base point, to which the second toner image in conveying which has been transferred to the sheet material at the transfer nip N is wound and transferred; a second detecting part configured to detect the second toner image transferred to the re-transfer roller 304; and an image deviation correction control part, configured to detect the image deviation amount between the first toner image and the second toner image using detection information obtained from the first detecting part and detection information obtained from the second detecting part, and control the operation of the second image forming apparatus 2 so that the image deviations are corrected from the image deviation amount detected. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
