<p>PURPOSE:To improve a treating efficiency and to output the image of a good quality by constituting the title device of an immobile body of the device and a mobile body of the device supported openably and closeably and arranging an optical scanning means and an image carrier on immobile body side of the device. CONSTITUTION:Inside a front cover 8, a transfer device 5 is set firmly, so that the mobile body 11 is constituted as a whole. The mobile body 11 is turnably supported to the immobile body 12 of an image forming device by a supporting shaft 10, and is opened forward widely at the time of an inspection for a maintenance. Since a photosensitive drum 1, a developing device 4, a cleaning device 6, and the optical scanning means are set on the immobile body 12 side of the device; a prescribed optical relation is kept. The mobile body 11 is light and the optical scanning means is arranged on the immobile body12 side of the device so that an impact and a vibration occurring at the time of an engagement are very light, and have no danger of adverse effects to an image-formation optical system, optical location, etc.; therefore, good image forming which is excellent in operability can be attained.</p> |
