Zusammenfassung:To provide an image forming device capable of enhancing productivity in the case where there is double-side printing in a consecutive printing job.SOLUTION: An image forming device has a paper discharging/reversing conveyance part comprising: a paper discharging/reversing drive roller which is a first conveyance roller; a paper discharging driven roller which is a second conveyance roller; and a reversing driven roller which is a third conveyance roller. A paper discharging roller pair is constituted by the paper discharging/reversing drive roller and the paper discharging driven roller 18a. A reversing roller pair is constituted by the paper discharging/reversing drive roller and the reversing driven roller 19a. When there is double-side printing in a consecutive printing job (YES in S2, Yes in S3), a printed sheet is discharged to a paper discharge tray which is a discharge part by the reversing roller pair 19 (S4).SELECTED DRAWING: Figure 11 【課題】連続印刷ジョブに両面印刷がある場合の生産性を高めることができる画像形成装置を提供する。【解決手段】画像形成装置は、第一搬送ローラたる排紙反転駆動ローラと、第二搬送ローラたる排紙従動ローラと、第三搬送ローラたる反転従動ローラとからなる排紙反転搬送部を有している。排紙反転駆動ローラと、排紙従動ローラ18aとにより排紙ローラ対を構成しており、排紙反転駆動ローラと反転従動ローラ19aとにより反転ローラ対を構成している。連続印刷ジョブに両面印刷があるとき(S2のYES、S3のYes)のときは、印刷済み用紙を、反転ローラ対19により排出部たる排紙トレイに排出する(S4)。【選択図】図11
