An electrophotographic copying apparatus is provided with a first body and a second body, the first body having a photosensitive member, a light source for exposing an original, an original supporting table movable relative to the light source with the original supported thereon, and a first optical system for projecting a first image information light reflected from the original onto the photosensitive member. The second body has a second optical system for projecting a second image information light onto the photosensitive member in the first body. Two copying modes are provided: a first mode for copying by the first image information light, and a second mode for copying by the second image information light. In the second mode, a controller positions a shutter member for blank exposure in the optical path in its retracted position prior to the copying in the second mode. Thus, solving the optical problems on the copying apparatus side and on the apparatus side for operating the recording medium and the higher functionalization of an optical system and/or the movement range of the movable original supporting table is changed during the original copying and during the copying of the recording medium to thereby enable the efficient use of the space.
