1. A sheet stacking apparatus comprising a pair of sheet alignment mechanisms disposed to face each other in a direction of conveyance of a sheet or in a direction orthogonal to the direction of conveyance,
each one of the pair of sheet alignment mechanisms including:
an aligning member configured to reciprocate with reference to the sheet;
an elastic member configured to extend due to reaction force generated in response to pressing force applied to an edge of the sheet by the aligning member when a size of the sheet is larger than a prescribed size;
a driver coupled to the aligning member via the elastic member; and
a driving source configured to transfer a driving force to the driver, further comprising a fixing member fixed to the driver,
wherein the aligning member includes:
a convex portion configured to face-contact the driver; and
an elongated hole defining a distance in which the aligning member reciprocates with respect to the sheet, and
wherein the fixing member is inserted into the elongated hole.
