The controller sets a state of the detecting portion at a first monitoring state in which a detection result of the detecting portion is acquired to detect presence or absence of the recording material by supplying the electric power to the detecting portion in a first cyclic period. In case that the detection result of the detecting portion changes in the first monitoring state, the controller switches the state of the detecting portion to a second monitoring state in which a detection result of the detecting portion is acquired by supplying the electric power to the detecting portion in a second cyclic period shorter than the first cyclic period."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Image forming apparatus","description":"An image forming apparatus includes a sheet feeding portion, a detecting portion, and a controller.
