| 摘要 |
An image forming apparatus includes two power cords (70, 80), a plurality of processing sections, a relay (91) and a control section (87). The relay (91) is switched between a conducting state where the two power cords (70, 80) can provide a bilateral supply of power between each other and a cut-off state where they cannot. The control section (87) stores an order of priority for the plurality of processing sections, switches the relay (91) from the cut-off state to the conducting state when a supply of power through either one power cord of the two power cords (70, 80) is cut off, and, by selecting a processing section sequentially according to the order of priority, causes load instruments included in the processing section currently selected to be driven while causing load instruments other than specified load instruments among load instruments included in processing sections currently not selected to stop. |

1. An image forming apparatus comprising:
two power cords that are each connected to a power source; a plurality of processing sections each of which includes one or more load instruments to which electric power is supplied by way of either of the two power cords; an input detecting section outputting signals that depend on whether or not an electric power supplied by way of each of the two power cords exists; a switching section that is switched between a conducting state in which the two power cords are permitted to provide a bilateral supply of power between each other and a cut-off state in which the two power cords are not permitted to provide the bilateral supply of power between each other; and a control section that stores a preset order of priority for the plurality of processing sections and upon determining, based on a signal inputted from the input detecting section, that an electric power cutoff situation in which a supply of power by way of either one power cord of the two power cords is cut off occurs, switches the switching section from the cut-off state to the conducting state, and that, by selecting one or more processing sections among the processing sections sequentially according to the order of priority, causes the one or more load instruments that are included in the processing section currently selected to be driven while causing the one or more load instruments other than one or more specified load instruments among load instruments that are included in processing sections currently not selected to stop. |
