Abstract

PURPOSE:To prevent mistaken copying by resetting an exposure mode at an automatic exposure mode or a standard manual exposure mode when operation is switched to a 2nd copying action from a 1st one. CONSTITUTION:A ROM 2 storing control programs, etc., and a RAM 3 storing transfer, exposure modes are connected to a CPU 1, while a copying process part 8 handling both original exposure and copying process and a sheet conveying part 9 controlling the convey of sheets are connected to an interface 5. When in a synthetic copying mode, for instance a developing tank is selected and set to the photosensitive drum, 'good or not' of the setting is judged. If it is normal, the exposure mode is set at the automatic exposure mode so that exposure errors will not occur in the next copying work. When an original is judged to be replaced, the mode is set at the automatic exposure mode so that exposure errors caused by a density difference between the current and previous originals can be eliminated. Thus copying errors can be eliminated.
