<p><P>PROBLEM TO BE SOLVED: To shorten the printing period even in double-sided printing of recording paper stopping across a conveying means and a paper re-feeding means. <P>SOLUTION: It is determined whether the recording paper stops across a fixing/delivering three-throw roller 17 and a paper re-feed roller 26. When it is determined that the recording paper does not stop across the fixing/delivering three-throw roller 17 and the paper re-feeding roller 26 (S803 YES), the recording paper is stopped by the paper re-feeding roller 26 until the second side of an image is developed by a data expansion section 113 (S812 and S813). When it is determined that the recording paper stops across the fixing/delivering three-throw roller 17 and the paper re-feeding roller 26 (S803 NO), the recording paper is stopped by an inverting roller 19 until the second side of the image is developed by the data expansion section 113 (S807-S820). <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
