A sheet feeding apparatus includes an apparatus body, a sheet feed portion, a sheet storage portion, and a resistance unit. The resistance unit includes a link member that is pivoted by coming in contact with the apparatus body when the sheet storage portion is mounted on the apparatus body toward a feed position, and is configured such that a distance between a normal line, in an contact surface with the apparatus body, and a pivot center becomes longer as the sheet storage portion approaches the feed position, a linear type oil damper generating a resistance force through a linear operation in accordance with pivoting of the link member, and a transmitting portion that is provided between the link member and the linear type oil damper, linearly moves due to the pivoting of the link member, and transmits the pivoting of the link member to the linear type oil damper.
