a return unit that a user operates in order to shift the image forming apparatus from the second power state to the first power state; a notification unit configured to, in a case where an object has been detected by the detection unit, notify a user of a position of the return unit; and a power-source control unit configured to, in a case where the return unit has been operated by the user, shift the image forming apparatus from the second power state to the first power state. ## Claims ### Claim 1 An image forming apparatus that enters a first power state in which a predetermined function is executable and a second power state in which the predetermined function is not executable, the image forming apparatus comprising: a detection unit configured to detect an object; a return unit that a user operates in order to shift the image forming apparatus from the second power state to the first power state; a notification unit configured to, in a case where an object has been detected by the detection unit, notify a user of a position of the return unit; and a power-source control unit configured to, in a case where the return unit has been operated by the user, shift the image forming apparatus from the second power state to the first power state. ### Claim 2 (depends on 1) The image forming apparatus according to claim 1, wherein, in a case where the detection unit does not detect the object, the notification unit does not notify a user of the position of the return unit. ### Claim 3 (depends on 1) The image forming apparatus according to claim 1, wherein the detection unit has a first detection range and a second detection range that is smaller than the first detection range, and wherein, in a case where an object has been detected in the first detection range by the detection unit, the notification unit notifies a user of the position of the return unit, and, in a case where an object has been detected in the second detection range by the detection unit, the power-source control unit shifts the image forming apparatus from the second power state to the first power state without operating the return unit by the user. ### Claim 4 (depends on 3) The image forming apparatus according to claim 3, wherein, in a case where an object has been detected in the second detection range by the detection unit, the notification unit does not notify a user of the position of the return unit. ### Claim 5 (depends on 1) The image forming apparatus according to claim 1, wherein the notification unit is a light-emitting section that is placed near the return unit. ### Claim 6 (depends on 5) The image forming apparatus according to claim 5, wherein a manner in which the light-emitting section performs illumination changes in accordance with a position of an object detected by the detection unit. ### Claim 7 (depends on 6) The image forming apparatus according to claim 6, wherein an interval, the light-emission section blinking at the intervals, or a brightness of the light-emission section changes in accordance with a position of an object detected by the detection unit. ### Claim 8 (depends on 1) The image forming apparatus according to claim 1, wherein the predetermined function is at least one of a copy function, a print function, and a fax function. ### Claim 9 (depends on 1) The image forming apparatus according to claim 1, wherein the detection unit includes an infrared sensor. ### Claim 10 (depends on 9) The image forming apparatus according to claim 9, wherein the detection unit includes an infrared array sensor in which infrared sensors are arranged. ### Claim 11 A method for controlling an image forming apparatus that enters a first power state in which a predetermined function is executable and a second power state in which the predetermined function is not executable, the method for controlling the image forming apparatus comprising: a step of detecting an object with a detection unit; a step of, in a case where an object has been detected by the detection unit, notifying a user of a position of a return unit that a user operates in order to shift the image forming apparatus from the second power state to the first power state; and a step of, in a case where the return unit has been operated by the user, shifting the image forming apparatus from the second power state to the first power state. ### Claim 12 An image forming apparatus that enters a first power state in which a predetermined function is executable and a second power state in which the predetermined function is not executable, the image forming apparatus comprising: a detection unit configured to detect an object; an acquisition unit configured to acquire, from a medium that stores identification information of a user who is to use the image forming apparatus, the identification information; and a notification unit configured to, in a case where an object has been detected by the detection unit, notify a user of a position of the acquisition unit. ### Claim 13 (depends on 12) The image forming apparatus according to claim 12, wherein, in a case where the detection unit does not detect the object, the notification unit does not notify a user of the position of the acquisition unit. ### Claim 14 (depends on 12) The image forming apparatus according to claim 12, wherein the notification unit is a light-emitting section that is placed near the acquisition unit. ### Claim 15 (depends on 14) The image forming apparatus according to claim 14, wherein a manner in which the light-emitting section performs illumination changes in accordance with a position of an object detected by the detection unit. ### Claim 16 A method for controlling an image forming apparatus that enters a first power state in which a predetermined function is executable and a second power state in which the predetermined function is not executable, the method for controlling the image forming apparatus comprising: a step of detecting an object with a detection unit; and a step of, in a case where an object has been detected by the detection unit, notifying a user of a position of an acquisition unit configured to acquire, from a medium that stores identification information of a user who is to use the image forming apparatus, the identification information.
