A sheet feeding device includes a sheet tray, a blower, a feeder, an illuminator, an imager, and circuitry. The sheet tray stacks sheets. The blower blows air to the sheets stacked on the sheet tray and floats an uppermost sheet of the sheets. The feeder feeds the uppermost sheet. The illuminator illuminates the uppermost sheet floating. The imager captures an image including the uppermost sheet illuminated by the illuminator. The circuitry adjusts an imaging condition based on the image captured by the imager.
