Abstract
An image formation apparatus is disclosed. The image formation apparatus includes a manuscript reading unit for reading a manuscript, a main power supply for supplying electric power to an alternating-current load and a direct-current load, and an auxiliary power supply that is capable of storing electric power for supplying electric power to the direct-current load. Power supply to the direct-current load is switched between the main power supply and the auxiliary power supply when reading the manuscript is not being carried out.
