PROBLEM TO BE SOLVED: To improve reliability as a network system and maintainability by reflecting the time of a master image forming device on a slave image forming device when the times held by the respective image forming devices are different in the case of performing network operation. SOLUTION: Plural image forming devices A and B provided with a clock 116 and a timer function for automatically turning on/off a power source at a set date are connected through a communication means 117 communicating an operation command, a state, image information, etc. By performing the network operation, the image information and the number of copies instructed from the master image forming device A are alloted to each slave image forming device B. When the times held by the image forming devices A and B are different, in such a case, a system controller 11 updates the time in the slave image forming device B based on the time held by the master image forming device A where network operation is performed. |
