Summary:PROBLEM TO BE SOLVED: To provide an image forming apparatus that can suppress the occurrence of fogging while suppressing deterioration of a photoreceptor.SOLUTION: An image forming apparatus performs, after image formation, reduction processing of reducing the absolute value of a charging bias to be applied to a charging part, separation processing of separating a developing roller from a photoreceptor to locate at a non-developing position after the reduction processing, and stopping processing of stopping the application of a developing bias to the developing roller after the separation processing.SELECTED DRAWING: Figure 6 【課題】感光体の劣化を抑制しつつ、かぶりの発生を抑制できる画像形成装置を提供する。【解決手段】画像形成後に、帯電部に印加する帯電バイアスの絶対値を小さくする低下処理と、低下処理後、現像ローラを離間させ非現像位置に位置させる離間処理と、離間処理後、現像ローラへの現像バイアスの印加を停止する停止処理とを行うことを特徴とする。【選択図】 図６
