Summary:PROBLEM TO BE SOLVED: To reduce an unnecessary polishing operation while suppressing a reduction in image quality.SOLUTION: An image forming apparatus comprises photoreceptors, chargers, transfer units, polishing units, and a control part. The control part executes image forming processing of forming developer images on the photoreceptors, detection processing of acquiring at least one of a charging current flowing in charging members and a transfer current flowing in transfer members, calculation processing of calculating an integrated current value based on an integrated value obtained by integrating the absolute value of the acquired current by time, and polishing processing of polishing the photoreceptors with the polishing units provided that the integrated current value reaches a threshold.SELECTED DRAWING: Figure 3 【課題】画質の低下を抑制しつつ、不要な研磨動作を減らすこと。【解決手段】画像形成装置は、感光体と、帯電器と、転写器と、研磨器と、制御部と、を備え、制御部は、感光体に現像剤像を形成する画像形成処理と、帯電部材に流れる帯電電流と、転写部材に流れる転写電流との少なくとも一方を、取得する検出処理と、取得した電流の絶対値を時間で積分した積分値に基づく積算電流値を算出する算出処理と、積算電流値が閾値に達したことを条件に、研磨器に感光体を研磨させる研磨処理と、を実行する。【選択図】図３
