An external communication unit receives, from a server, update information including information indicating an update target device whose software is to be updated among devices and information indicating a generation source device among the devices, the generation source device being installed with generation source software that is a source for generating update data to be used for updating update target software installed in the update target device. An update data generating unit generates, on the basis of the update information, the update data using the generation source software installed in a host device of the update data generating unit, when the host device is the generation source device. A software update unit updates, on the basis of the update information, the update target software installed in a host device of the software update unit using the generated update data, when the host device is the update target device.
