Summary:To reduce toner scattered inside a device due to an air flow for cooling exposure means.SOLUTION: An image forming device comprises: a photoreceptor; exposure means that forms a latent image on the photoreceptor; development means that develops the latent image formed on the photoreceptor by a toner; a photoreceptor support member that guides the photoreceptor along an axial line direction of the photoreceptor and removably supports it; a development support member that guides the development means along the axial line direction and removably supports it; an exposure support member that is disposed between the photoreceptor support member and the development support member and integrally supports the exposure means, and that communicates with the exposure means and is moved, integrally with the exposure means, to an exposure position where the photoreceptor is exposed, and to a retreat position where the photoreceptor is retracted from the exposure position; an exposure cooling unit that communicates with the exposure support member, and is configured to cool the exposure means by an air flow through the exposure support member; and a sealing member that seals, at the exposure position, a gap between the exposure support member and the development support member, and a gap between the exposure support member and the photoreceptor support member.SELECTED DRAWING: Figure 22 【課題】露光手段を冷却する気流による装置内部でのトナーの飛散を低減する。【解決手段】感光体と、感光体に潜像を形成する露光手段と、感光体に形成された潜像をトナーにより現像する現像手段と、感光体を感光体の軸線方向に沿って案内し、着脱自在に支持する感光体支持部材と、現像手段を軸線方向に沿って案内し、着脱自在に支持する現像支持部材と、感光体支持部材と現像支持部材との間に設けられ、露光手段を一体に支持し、露光手段に連通し、露光手段と一体となって、感光体を露光する露光位置と、露光位置から退避した退避位置と、に移動される露光支持部材と、露光支持部材に連通し、露光支持部材を通して露光手段を気流により冷却するための露光冷却ユニットと、露光位置において、露光支持部材と現像支持部材との間の隙間および露光支持部材と感光体支持部材との間の隙間を封止する封止部材と、を備える。【選択図】 図２２
