To provide an image forming apparatus that can accurately execute, when necessary, processing for reducing the frictional force between image carriers and cleaning members.SOLUTION: An image forming apparatus 100 comprises: image carriers 1; cleaning members 61 that are in contact with the image carriers to remove toner from the image carriers; driving sources 21 that drive the image carriers; speed detection means 24 that detect the rotation speed of the image carriers; and control means 31 that can execute frictional force reduction processing for reducing the frictional force between the image carriers and cleaning members. The control means executes the frictional force reduction processing according to information on a variation in rotation speed of the image carriers acquired on the basis of a result of detection performed by the speed detection means.SELECTED DRAWING: Figure 8 【課題】像担持体とクリーニング部材との間の摩擦力を低減する処理を精度良く必要時に実行することのできる画像形成装置を提供する。【解決手段】画像形成装置１００は、像担持体１と、像担持体に接触し像担持体からトナーを除去するクリーニング部材６１と、像担持体を駆動する駆動源２１と、像担持体の回転速度を検知する速度検知手段２４と、像担持体とクリーニング部材との間の摩擦力を低減する摩擦力低減処理を実行することが可能な制御手段３１と、を有し、制御手段が、速度検知手段の検知結果に基づいて取得した像担持体の回転速度変動に関する情報に応じて、摩擦力低減処理を実行する構成とする。【選択図】図８
