PURPOSE:To display plural contents by means of a small operation panel by providing the title device with a storage means for individually counting and storing the using frequency of a photosensitive body and a developing means and displaying the contents in accordance with the kind of key operation in a count mode. CONSTITUTION:When a power supply switch is turned on, an operation signal is outputted from a CPU 2 to a process device through an I/O 7. The timing of count input to memories MY32, MM33, MC34 in a RAM 3 is performed at the same time as a command outputted to one of developing devices 51-53. The memories MY32, MM33, MC34 are prepared for yellow, magenta and cyan and total contents are stored in a memory Mr35. When a mode changing switch 12 is depressed, an input signal is inputted to the CPU 2 through an I/O 8 and the CPU 2 sets up a flag F31 to a count mode and switches ten keys 11 to the count mode. When the ten keys 11 are operated, the contents of each color are displayed on a display part 13, so that the operation panel can be miniaturized. |
