a first obtaining unit that obtains a usage amount of the expendable from a time point of detection of a situation where a remaining amount of the expendable in the expendable replenishment container is lower than a predetermined value;
a second obtaining unit that obtains a remaining amount in the tank;
a first determination unit that determines a state of the remaining amount of the expendable in the expendable replenishment container by comparing the usage amount obtained by the first obtaining unit and the remaining amount in the tank obtained by the second obtaining unit with thresholds set respectively for the usage amount and the remaining amount; and
a detection unit that detects the situation where the remaining amount of the expendable in the expendable replenishment container is lower than the predetermined value, in a case where the state determined by the first determination unit is a remaining amount low state.
