1. An image forming apparatus comprising:
a controller configured to control an image forming operation of the image forming apparatus; and
a detector configured to detect a state of the image forming apparatus by being supplied with electric power and to output a signal indicating the state of the image forming apparatus to the controller,
wherein an operation state of the image forming apparatus includes a normal state in which electric power is supplied to respective portions in the image forming apparatus and a power saving state in which the electric power is supplied to a part of the portions in the image forming apparatus,
wherein in a case of the power saving state in which an electric power is supplied to a part of the portions in the image forming apparatus, an operation state of the detector includes a first state in which a detection result of said detector is acquired by supplying the electric power to said detector in a first time period and a second state in which a detection result of said detector is acquired by supplying the electric power to said detector in a second time period longer than the first time period.
