Claim:
1. An image forming apparatus comprising: an image forming section configured to form an image on a recording material; a user interface configured to be operated by a person; a first detector comprising a pyroelectric sensor, the first detector being configured to detect a person in a first area that is set obliquely downward from a horizontal plane with respect to a front view of the image forming apparatus; a second detector configured to detect the person in a second area that is smaller than the first area, the second area separated from the first area with respect to the front view of the image forming apparatus or a portion of the second area overlapping the first area when viewed from above with respect to the front view; and at least one processor configured to switch between a first condition in which the image forming apparatus consumes a first amount of electric power and a second condition in which the image forming apparatus consumes a second amount of electric power, the second amount being less than the first amount, wherein electric power required for the first detector to detect the person is less than electric power required for the second detector to detect the person, wherein in response to the first detector detecting the person, electric power required for the second detector to detect the person is supplied to the second detector, wherein in response to the second detector detecting the person, the at least one processor switches from the second condition to the first condition, wherein, when viewed from above with respect to the front view, the first detector is provided so that a position opposing the first detector with the user interface being disposed therebetween is not included in the first area, and wherein the first detector is provided so that positions that are adjacent to trays of the image forming apparatus are not included in the first area when viewed from above with respect to the front view.
