摘要：
A sheet feeding device includes a first roller that draws a recording medium at a first position and feeds the recording medium; a friction pad that comes into contact with the first roller with a predetermined contact pressure at a second position that is close to and downstream of the first position in a conveying direction of the recording medium and nips the recording medium with the first roller to convey the recording medium in the conveying direction; and a second roller that comes into contact with the first roller at a third position that is close to and downstream of the second position in the conveying direction and nips the recording medium with the first roller.
