| description | To provide an image forming apparatus that can appropriately remove reversely-charged toner accumulated on a charging roller.SOLUTION: When a control unit collects reversely-charged toner on a charging roller 53 while not executing image forming processing, it executes separation processing of controlling a contact and separation mechanism to locate a developing roller 61 at a separation position, reversely-charged toner discharge processing of applying bias to the charging roller 53 so as to move the reversely-charged toner on the charging roller 53 from the charging roller 53 to a photoconductor drum 52, and drum reversely-charged toner collection processing of, after the reversely-charged toner discharge processing, transferring the reversely-charged toner on the photoconductor drum 52 to a transfer belt 73 from the photoconductor drum 52 and collecting the reversely-charged toner on the transfer belt 73 by using a belt cleaner 90.SELECTED DRAWING: Figure 15
【課題】帯電ローラに蓄積した逆帯電トナーを適切に除去することができる画像形成装置を提供する。【解決手段】制御部は、画像形成処理を実行していないときに、帯電ローラ５３上の逆帯電トナーを回収する際に、接触離間機構を制御することで現像ローラ６１を離間位置に位置させる離間処理と、帯電ローラ５３に、帯電ローラ５３上の逆帯電トナーが帯電ローラ５３から感光ドラム５２に移動するようなバイアスを印加する逆帯電トナー吐出処理と、逆帯電トナー吐出処理の後、感光ドラム５２上の逆帯電トナーを、感光ドラム５２から転写ベルト７３に転写し、転写ベルト７３上の逆帯電トナーをベルトクリーナ９０で回収するドラム逆帯電トナー回収処理と、を実行する。【選択図】図１５ |
