IMAGE FORMING APPARATUS

To provide means that makes it possible to smoothly perform maintenance work of an image forming apparatus.SOLUTION: When a first rotating member and a photoreceptor unit holding member are engaged and engagement of the photoreceptor unit holding member and an apparatus main body part is released, the first rotating member and a second rotating member integrally rotate to open an opening and separate a photoreceptor unit from the apparatus main body part. When the engagement of the first rotating member and the photoreceptor unit holding member is released and the photoreceptor unit holding member and the apparatus main body part are engaged, the first rotating member rotates to separate an exposure device from the photoreceptor unit.SELECTED DRAWING: Figure 18 【課題】画像形成装置の保守作業を円滑に行えるようにする手段を提供する。【解決手段】第１の回動部材と感光体ユニット保持部材とが係合され、かつ、感光体ユニット保持部材と装置本体部との係合が解除されると、第１の回動部材が第２の回動部材と一体となって回動して開口を開放するとともに、感光体ユニットを装置本体部から離間させ、第１の回動部材と感光体ユニット保持部材との係合が解除され、かつ、感光体ユニット保持部材と装置本体部とが係合されると、第１の回動部材が回動し、露光装置を感光体ユニットから離間させる。【選択図】 図１８
