A power supplying control apparatus includes a transition unit that causes a control apparatus to transition to one of a power supplied state that causes power to be supplied and a power shutoff state that shuts off the supplying of power, and a determining unit that determines a transition target of the transition unit in accordance with a first time period and a second time period, the first time period having a length of time beyond which no further memory space is available from a second memory, and thus being determined by a transmission and reception speed of information to a communication line network and a storage capacity of the second memory, the second time period being so long as to enable information stored on the second memory to be stored on a first memory in the power shutoff state.
