Abstract
A sheet feeding device includes a sheet stacker, a conveyor, a sensor, circuitry, and a changing unit. The conveyor conveys a sheet from the sheet stacker by suction. The sensor detects a state of the sheet before the sheet is conveyed from the sheet stacker. The circuitry determines the state of the sheet based on a detection result of the sensor. The changing unit changes a passage to convey the sheet based on a determination result.
