PROBLEM TO BE SOLVED: To provide a power source control system controlling the power sources of plural image forming devices so that a user may not feel inconvenient while saving power. SOLUTION: Plural copying machines 2 to 5 are connected to a power source judging processing device 1 by using communication lines 6a to 6d, and the device 1 judges whether the state of the power source of each copying machine is an on-state or an off-state or a standby-state. Based on the judgement, the device 1 controls the power source of the copying machines 2 to 5 so that one of the copying machines 2 to 5 may be always in the standby state. |
