Abstract:
There is provided an image forming apparatus includes: a first electric-power supply path, through which electric power is supplied from a commercial electric power supply to the apparatus when the first electric-power supply path is in closed state; a second electric-power supply path, through which electric power is supplied from the commercial electric power supply to the apparatus when, at least, a detecting unit has detected that the first electric-power supply path is in the open state; and a plurality of drive-voltage generating units, each of which converts a voltage fed from the electric power supply through any one of the first electric-power supply path and the second electric-power supply path into a predetermined drive voltage; a plurality of systems, to each of which the drive voltage converted by a corresponding one drive-voltage generating unit of the drive-voltage generating units is fed.
