Image forming apparatus having a sheet reversing device |
摘要 |
In an image forming apparatus, a length of a transporting passage between an induction roller pair and a reversal roller pair and a length of a transporting passage between the reversal roller pair and a feed roller pair are respectively set smaller than the smallest length in the transporting direction of a sheet used in an image forming apparatus. A time till the rotation of the reversal roller pair is switched to the forward rotation after a rear end of the sheet having a length in the transporting passage of 8.5 inch after reversal has passed through the reversal roller pair can be set shorter than a time when a leading end of a succeeding sheet inducted into a pull-in passage reaches the reversal roller pair.
