Claim 0:
1. An image forming apparatus comprising:
a plurality of mounting surfaces provided on a main body of the image forming apparatus and on which discharged paper is placed after image formation;
a human sensor provided in the main body;
a plurality of paper sensors provided on the plurality of mounting surfaces, wherein power supply to each of the plurality of paper sensors is stopped in a sleep state of the main body;
a processor configured to:
control a transition to the sleep state of the main body based on an occurrence of a transition event;

control return from the sleep state of the main body, based on the detection of a person by the human sensor;
determine whether a state of the plurality of mounting surfaces is a paper-absence state or a paper-presence state according to output signals of the plurality of paper sensors in the transition to the sleep state after the occurrence of the transition event, wherein the paper-absence state is a state where there is no paper on the plurality of mounting surfaces, the paper-presence state is a state where there is a paper on the plurality of mounting surfaces;
perform control such that
in a case of the state being the paper-presence state in the transition to the sleep state, a nearby person approaching the main body is included in a detection target of the human sensor in the sleep state, and a passerby passing near the main body is not included in the detection target in the sleep state, and
in a case of the state being the paper-absence state in the transition to the sleep state, the nearby person and the passerby are included in the detection target in the sleep state; and

control notification of paper remaining in a case where there is a paper on the plurality of mounting surfaces after the return from the sleep state.
