image forming apparatus; a first covering provided in front of the human presence sensor; and a second covering provided in front of the first covering, the second covering being configured not to interfere with detection of a detection target by the human presence sensor. ## Claims ### Claim 1 An image forming apparatus comprising: a human presence sensor that detects a user who uses the image forming apparatus; a first covering provided in front of the human presence sensor; and a second covering provided in front of the first covering, the second covering being configured not to interfere with detection of a detection target by the human presence sensor, wherein the first covering and the second covering are aligned along a light emitting path of measurement light emitted from the human presence sensor. ### Claim 2 (depends on 1) The image forming apparatus according to claim 1, wherein the first covering is black. ### Claim 3 (depends on 2) The image forming apparatus according to claim 2, wherein the second covering is transparent. ### Claim 4 (depends on 1) The image forming apparatus according to claim 1, wherein the first covering is a covering structured to make the human presence sensor invisible from outside. ### Claim 5 (depends on 1) The image forming apparatus according to claim 1, wherein the second covering is a covering structured to make the first covering visible from outside. ### Claim 6 (depends on 1) The image forming apparatus according to claim 1, wherein the human presence sensor is a ranging sensor that includes a light source that emits the measurement light, and a position detecting element that detects a position at which reflected light of the measurement light is received, and the ranging sensor measures a distance to the detection target based on an output value of the position detecting element. ### Claim 7 (depends on 6) The image forming apparatus according to claim 6, wherein the second covering is made of a material capable of transmitting a wavelength of measurement light used by the human presence sensor. ### Claim 8 (depends on 6) The image forming apparatus according to claim 6, wherein the second covering is made of a material with a transmittance of 70% or greater in a band where a wavelength of light is greater than or equal to 800 nm and less than or equal to 940 mm. ### Claim 9 (depends on 6) The image forming apparatus according to claim 6, wherein, while the second covering is covering the human presence sensor, a distance between the first covering and the second covering is configured not to interfere with detection of the detection target by the human presence sensor. ### Claim 10 (depends on 9) The image forming apparatus according to claim 9, wherein, while the second covering is covering the human presence sensor, the distance between the first covering and the second covering is configured to be less than or equal to 5 cm. ### Claim 11 (depends on 1) The image forming apparatus according to claim 1, wherein the second covering is configured to be openable/closable in front of the image forming apparatus, and is configured to be capable of changing between a state of covering the human presence sensor and a state of not covering the human presence sensor. ### Claim 12 (depends on 2) The image forming apparatus according to claim 2, wherein the second covering is configured to be openable/closable in front of the image forming apparatus, and is configured to be capable of changing between a state of covering the human presence sensor and a state of not covering the human presence sensor. ### Claim 13 (depends on 3) The image forming apparatus according to claim 3, wherein the second covering is configured to be openable/closable in front of the image forming apparatus, and is configured to be capable of changing between a state of covering the human presence sensor and a state of not covering the human presence sensor. ### Claim 14 (depends on 4) The image forming apparatus according to claim 4, wherein the second covering is configured to be openable/closable in front of the image forming apparatus, and is configured to be capable of changing between a state of covering the human presence sensor and a state of not covering the human presence sensor. ### Claim 15 (depends on 5) The image forming apparatus according to claim 5, wherein the second covering is configured to be openable/closable in front of the image forming apparatus, and is configured to be capable of changing between a state of covering the human presence sensor and a state of not covering the human presence sensor. ### Claim 16 (depends on 6) The image forming apparatus according to claim 6, wherein the second covering is configured to be openable/closable in front of the image foaming apparatus, and is configured to be capable of changing between a state of covering the human presence sensor and a state of not covering the human presence sensor. ### Claim 17 (depends on 7) The image forming apparatus according to claim 7, wherein the second covering is configured to be openable/closable in front of the image forming apparatus, and is configured to be capable of changing between a state of covering the human presence sensor and a state of not covering the human presence sensor. ### Claim 18 (depends on 8) The image forming apparatus according to claim 8, wherein the second covering is configured to be openable/closable in front of the image forming apparatus, and is configured to be capable of changing between a state of covering the human presence sensor and a state of not covering the human presence sensor. ### Claim 19 (depends on 9) The image forming apparatus according to claim 9, wherein the second covering is configured to be openable/closable in front of the image forming apparatus, and is configured to be capable of changing between a state of covering the human presence sensor and a state of not covering the human presence sensor. ### Claim 20 (depends on 10) The image forming apparatus according to claim 10, wherein the second covering is configured to be openable/closable in front of the image forming apparatus, and is configured to be capable of changing between a state of covering the human presence sensor and a state of not covering the human presence sensor.
