PURPOSE:To make one kind of electrophotographic copying device comply with plural uses by providing a photosensitive body exchanging means capable of exchanging plural photosensitive bodies and an image forming condition switching means for switching one or more image forming conditions corresponding to the respective photosensitive bodies. CONSTITUTION:This device is provided with the photosensitive body exchanging means capable of exchanging plural photosensitive bodies and the image forming condition switching means for switching one or more image forming conditions corresponding to the respective photosensitive bodies. Namely, when the type of the photosensitive body used is selected by an exposure wavelength selection switch 20, a control circuit 21 actuates driving means 22 and 23 corresponding to the photosensitive body used, and exposure is performed after image exposure wavelength and pre-exposure wavelength are made appropriate. Thus, even in the case of one electrophotographic copying device, the photosensitive body having characteristic appropriate for a use purpose is selected and exchanged to another one among plural photosensitive bodies, and an optimum copy fitted for the characteristic of the exchanged photosensitive body is obtained. |
