If the preset transition time is not 0, the CPU 61 calculates the time T by adding the preset transition time to the end time of the image forming process (S7), and calculates the calculated time. T is compared with time information Tmax (S8). If the calculated time IJT is later than the time information Tmax, the CPU 61 sets the value of the time T as the content of the time information Tmax (S9).
