A sheet feeding apparatus and an image forming apparatus capable of ensuring reliability of meshing of gears at low cost are provided. When a sheet feeding cassette is mounted to a printer body, a lifter gear provided to a lifter shaft of a lifter plate which lifts a sheet supporting plate is engaged with a first lifter idler gear, and the lifter gear is rotated by rotations of the first lifter idler gear by a drive of a lifter motor, and thereby the sheet supporting plate is lifted. And, displacement of the lifter gear is restricted by a load applied to the lifter gear by a restriction portion provided with an auxiliary support shaft which is provided to an opening portion formed in the lifter gear and the sheet feeding cassette to enter the opening portion when lifting the sheet supporting plate.
