PURPOSE:To improve printing ability in a copying machine and the like by branching a curved passage from a carrying passage in an image forming part lower stream in such a manner as to be capable of cutting and connecting, and connecting it to one end of a bottom feed type middle stocker through a sheet reversing means, and connecting a paper feeding mean of the stocker to the upstream side carrying passage of the image forming part through a sheet refeeding passage. CONSTITUTION:In a sheet carrying passage 7, an image forming part 1 and fixing roller 8 are disposed, and on the lower stream side of the fixing roller 8, a curved passage 10 is branched through a separating claw 9 for selectively switching a sheet in directions B and C. The lower stream end of the curved passage 10 is connected to a middle stocker 11 through a reversing device 16 in the course. A refeeding feed roller 11 is disposed under the middle stocker 11, and the feed side of the sheet carrying passage 7 is connected to the feed roller 11 through a refeed passage 18. In the refeed passage 18, a sheet separating means 19 and a carrying roller 20 are disposed. |
