Summary:To prevent deterioration of an image such as chipping of the image due to a process cartridge mounted in an apparatus body.SOLUTION: An image forming apparatus 1 has a process cartridge 50 that includes an electrifying wire 52 for electrifying one of photoconductor drums 51y, 51m, 51c, and 51k and is removably attached to an apparatus body 1a. The image forming apparatus has: a cleaning unit 200 that is attached to the process cartridge 50 and is movable between a cleaning position where it cleans the electrifying wire 52 and a retracted position where it is retracted from the cleaning position; and a slide guide 12 that guides an operating unit 240 located at the cleaning position to the retracted position when the process cartridge 50 is mounted in the apparatus body 1a.SELECTED DRAWING: Figure 8 【課題】装置本体に装着されたプロセスカートリッジによる画像が欠ける等の画像の劣化を防ぐこと。【解決手段】感光ドラム５１ｙ、５１ｍ、５１ｃ及び５１ｋを帯電させる帯電ワイヤ５２を備えるプロセスカートリッジ５０が装置本体１ａに着脱自在に装着される画像形成装置１は、プロセスカートリッジ５０に取り付けられると共に、帯電ワイヤ５２を清掃する清掃位置と、清掃位置から退避した退避位置と、の間で移動可能な清掃ユニット２００と、プロセスカートリッジ５０が装置本体１ａに装着される際に、清掃位置に有る操作部２４０を退避位置に案内するスライドガイド１２と、を有する。【選択図】図８
