PURPOSE:To obtain easily a multicolor copy by a simple operation, by providing plural developing devices so that they can be switched automatically. CONSTITUTION:A copying mode, a combination of plural developing devices, etc. can be selected by an operating part 11. Also, this device is provided with a mode for designating the developing device to be used, of the developing devices, and a mode which has prescribed in advance automatically a color of the first face of continuous copying and the second face. In this state, with regard to the case when the first face and the second face are copied in black and red, respectively, it is illustrated. An electrostatic latent image is obtained by scanning the original by the first scanning mirror and an illuminating lamp 14, and thereafter, visualized by a black developing device, a designated copying paper is fed to a photosensitive drum 1 through a resist roller 28 from a feed paper roller, from a feed paper port of a cassette 25 or 26, and copying is executed. Subsequently, it is visualized by a red developing device, and copying of the second face is executed in the same way. In this way, a multicolor copy can be obtained easily by bringing the original to an exposure scan, and switching automatically the developing device at every scan. |
