A sheet feeding device includes a feeding guide configured to guide a sheet, a separation unit configured to separate the sheet from a plurality of sheets, and a holding portion configured to hold the separation unit. The separation unit may be configured to be removably attached to the holding portion. Further, the holding portion may be configured to move from a first position where the holding portion holds the separation unit in contact with a pressing portion to a second position where the holding portion holds the separation unit away from the pressing portion while remaining connected to the feeding guide. The pressing portion may be configured to press the separation unit toward a feeding roller when the holding portion is in the first position.
