PURPOSE:To save resources and to prevent environmental pollution by reducing the consumption of commercial power. CONSTITUTION:When a solar battery panel 109 gets sunshine, etc., and the generation of power is started, the generated power is consumed as an energy source for the operation of the image forming device. The commercial power 110 is saved by the amount of energy supplied by the solar battery panel 109. The power generated by it is consumed as the energy source of the image forming device and simultaneously stored in a secondary battery 107 by a charging device 106. The stored power is used when a capacity to generate the power in the solar battery panel 109 is small, that is, in nighttime, etc. |
