Zusammenfassung:To provide an image forming apparatus and a developer discharge method that can prevent an increase in the amount of deteriorated developer in a developer supply unit.SOLUTION: An image forming apparatus 100 comprises: a discharge processing unit 71 that executes discharge processing of causing a developing device to discharge toner in a preset discharge amount; and a setting processing unit 72 that, when the discharge processing is executed and the discharge processing is not the first discharge processing after a predetermined reference time, sets the discharge amount in the discharge processing to be executed based on the count value of the number of prints from the execution of the preceeding discharge processing and the count value of the number of prints from the reference time.SELECTED DRAWING: Figure 2 【課題】現像剤供給部内における劣化した現像剤の増加を抑制可能な画像形成装置、及び現像剤排出方法を提供すること。【解決手段】画像形成装置100は、予め設定された排出量のトナーを現像装置から排出させる排出処理を実行する排出処理部71と、前記排出処理が実行される場合であって当該排出処理が予め定められた基準時後の最初の前記排出処理ではない場合に、直前の前記排出処理の実行時からの印刷枚数のカウント値、及び前記基準時からの印刷枚数のカウント値に基づいて、実行される前記排出処理の前記排出量を設定する設定処理部72と、を備える。【選択図】図2
