Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a sheet ejecting apparatus, a sheet processing apparatus, and an image forming apparatus that can prevent the alignment performance of sheets from being deteriorated without lowering productivity.SOLUTION: A control part controls a wind velocity according to a basis weight of a sheet P that is blown out from an paper ejection fan 702. while blowing out air downward the sheet P ejected by an upper ejection roller 120 via the paper ejection fan 702. The control part increases the wind velocity of the paper ejection fan 702 according to the basis weight of the sheet P based on information of the basis weight from an input part for inputting the basis weight information of the sheet P when the basis weight of the sheet P is equal to or over a predetermined one. The control part controls the wind velocity of the paper ejection fan 702, by which velocity the sheet P whose rear end contacts with a stacking wall 100a is not moved in a sheet ejection direction when the basis weight of the sheet P is equal to or larger than the predetermined one.
