Summary:To provide an image forming apparatus that can prevent toner from being deteriorated by paper powder attached to magnetic rollers.SOLUTION: A control unit 200 of an image forming apparatus can execute a monochrome printing operation of rotating four photoconductor drums 51 and a magnetic roller 61K and stopping magnetic rollers 61Y, 61M, 61C. The control unit 200 can execute paper powder recovery operation. The paper powder recovery operation includes executing first moving processing of moving paper powder D attached to the magnetic rollers 61Y, 61M, 61C to photoconductor drums 51Y, 51M, 51C from the magnetic rollers 61Y, 61M, 61C, second moving processing of moving the paper powder D moved to the photoconductor drums 51Y, 51M, 51C in the first moving processing to a conveying belt 73 from the photoconductor drums 51Y, 51M, 51C, and paper powder recovery processing of recovering, with a belt cleaning roller 101, the paper powder D moved to the conveying belt 73 in the second moving processing and storing it in a recovery container 104.SELECTED DRAWING: Figure 4 【課題】磁気ローラに付着した紙粉によってトナーが劣化するのを抑制することができる画像形成装置を提供する。【解決手段】画像形成装置の制御部200は、4つの感光ドラム51および磁気ローラ61Kを回転させ、磁気ローラ61Y,61M,61Cを停止させるモノクロ印刷動作を実行可能である。制御部200は、紙粉回収動作を実行可能である。紙粉回収動作では、磁気ローラ61Y,61M,61Cに付着した紙粉Dを、磁気ローラ61Y,61M,61Cから感光ドラム51Y,51M,51Cに移動させる第1移動処理と、第1移動処理によって感光ドラム51Y,51M,51Cに移動させた紙粉Dを、感光ドラム51Y,51M,51Cから搬送ベルト73に移動させる第2移動処理と、第2移動処理によって搬送ベルト73に移動させた紙粉Dを、ベルトクリーニングローラ101によって回収し、回収物収容器104に収容する紙粉回収処理とを実行する。【選択図】図4
