That is, the image processing apparatus 10 according to the present embodiment includes a fluctuation generating portion 31 and a connection identifying portion 32, as illustrated in FIG. 1. The fluctuation generating portion 31 fluctuates an output power of the power supply portion that supplies power to the loads. The connection identifying portion 32 identifies a connection relationship between the power supply portion and the loads based on a correlative relationship between a fluctuation of the output power and a fluctuation of the power supplied to the loads. In the present embodiment, as one example, the fluctuation generating portion 31 and the connection identifying portion 32 are provided in the main body control portion 16 as one of the functions of the main body control portion 16.
