PURPOSE:To increase a copying speed, by selectively setting a start time point for generating an image in the following copying step, in accordance with length of the carrying direction of copying paper which has been carried through a prescribed route in the previous process, in case of continuous copying. CONSTITUTION:In case when a copying process is executed continuously 2 times or plural times, a time interval between a time point when the first supporting frame body of an optical system 26 has reached a detecting position of the third optical system detector in the previous copying steps, and a time point when the first supporting frame body of the optical system 26 reaches the detecting position of the third optical system detector, that is to say, a time interval between a time point when generation of an image onto a photosensitive body 12 has been started in the previous copying step, and a time point when generation of an image has been started in the following copying step is different depending on length of the carrying direction of copying paper which has been carried through a copying paper carrying route 56 in the previous copying step. Accordingly, in accordance with the length of this carrying direction, a start time point of generation of an image in the following step is set. |
