1. An image forming apparatus for performing job processing, the image forming apparatus comprising:
a cooling unit configured to cool an inside of an enclosure of the image forming apparatus; a heating unit arranged inside of the enclosure of the image forming apparatus; a power generating unit configured to generate power by heat of the heating unit; an external power source configured to store the power generated by the power generating unit; a power supply control unit configured to supply power to the cooling unit from the external power source when the cooling unit starts, after the cooling unit starts by the power from the external power source, switch a power source of the cooling unit from the external power source to the power generating unit when a predetermined time elapses; a first determination unit configured to determine whether the cooling unit is capable of being driven by a power amount suppliable from the external power source,
wherein, if the first determination unit determines that the cooling unit is capable of being driven by the power amount suppliable from the external power source, the power supply control unit switches the power source of the cooling unit from the external power source to the power generating unit according to a time elapsed from when the cooling unit has been driven by the power from the external power source, andwherein, if the first determination unit determines that the cooling unit is incapable of being driven by the power amount suppliable from the external power source, the power supply control unit switches the power source of the cooling unit from the power supplying unit to the power generating unit according to the time elapsed from when the cooling unit has been driven by the power from the power supplying unit; and a second determination unit configured to determine whether the cooling unit is capable of being driven by a power amount suppliable from one of the power generating unit and the external power source,
wherein, if the second determination unit determines that the cooling unit is incapable of being driven by the power amount suppliable from the power generating unit and the cooling unit is capable of being driven by the power amount suppliable from the external power source, after the cooling unit has been driven by the power from the external power source, the power supply control unit switches the power source of the cooling unit from the external power source to the power generating unit according to a cooling state of the cooling unit, andwherein, if the second determination unit determines that the cooling unit is incapable of being driven by the power amount suppliable from one of the power generating unit and the external power source, after the cooling unit has been driven by the power from the power supplying unit, the power supply control unit switches the power source of the cooling unit from the power supplying unit to the power generating unit according to the cooling state of the cooling unit. |
