PURPOSE:To prevent generation of mis-copying by an inadequate density by providing means which cancel copying conditions set when a when a manual density adjusting mode is selected during warming up. CONSTITUTION:The control over the entire part of a copying machine is executed by a CPU 20 and the processing program thereof is previously stored in a ROM 21. A copying process part including an operating part, sensor part, optical system, image forming process part, paper feeding part, etc., is connected via an I/O 23 to the CPU 20. These devices are operated by the supply of electric power from a main power supply 24. Keys for inputting various copying conditions and display panel for displaying these conditions, etc., are provided to the operating part. The CPU 20 cancels the respective copying conditions and displays that the copying machine is in the state of not starting the copying process after the end of the warming up when the manual density adjusting mode is selected during the warming up. The generation of the mis-copying is thereby prevented. |
