a first detection unit configured to detect an object in a detection range;
an operation unit configured to receive an input caused by the object being in the detection range regardless of whether the
object is detected, wherein receipt of the input shifts the image forming apparatus from the second electric power state to
the first electric power state;

a control unit configured to, when the first detection unit detects the object or the operation unit receives the input, shift
the image forming apparatus from the second electric power state to the first electric power state; and

a notification unit configured to provide information indicating a failure condition of the first detection unit if the image
forming apparatus has shifted from the second electric power state to the first electric power state as a result of the operation
unit receiving the input.
