EXPOSURE WINDOW COMPONENT, EXPOSURE DEVICE USING THE SAME, AND IMAGE FORMING DEVICE

PROBLEM TO BE SOLVED: To improve cleaning performance to an exposure window component.SOLUTION: An exposure window component 3 is arranged separately from an exposure device casing 11, has an opening 2 through which light from the exposure device casing 11 passes, and is mounted on the opening 2, and includes: a transmissive transmission member 4 for passing the light from the exposure device casing 11 through, a holding frame 5 for holding the transmission member 4; a receiving member 6 which is arranged on an edge of the opening 2, receives the holding frame 5 when mounting the transmission member 4, and detachably supports the transmission member 4; and a gripping part 7 which is arranged on a part of the holding frame 5, and grips when attaching and detaching the transmission member 4. An exposure device provided with the exposure window component 3 and an image forming device include an embodiment where the gripping part 7 can be gripped when pulling out an image holding body 15, and an embodiment where the image holding body 15 has a protrusion part 17 protruding from an end part in a pull-out direction toward a radial direction, and the protrusion part 17 has a projection part 18 for pushing the holding frame 5 into a predetermined position.SELECTED DRAWING: Figure 1 【課題】露光窓部品に対する清掃性を改善する。【解決手段】露光装置筐体１１から分離して設けられ、露光装置筐体１１からの光が通過する開口２を有し、当該開口２に装着される露光窓部品３であって、露光装置筐体１１からの光を通過させる透過性の透過部材４と、透過部材４を保持する保持枠５と、開口２縁に設けられ、透過部材４を装着するときに保持枠５を受け止め、透過部材４を着脱可能に支持する受止め部材６と、保持枠５の一部に設けられ、透過部材４を着脱するときに把持する把持部７と、を備える。更に、露光窓部品３を備えた露光装置や画像形成装置としては、像保持体１５を引き抜いたときに把持部７を把持可能とする態様や、像保持体１５は引き抜き方向の端部に径方向に向かって突出する張出部１７を有し、当該張出部１７には保持枠５を予め決められた位置まで押し込む突起部１８を有する態様も含む。【選択図】図１
