To provide an image forming apparatus capable of filing a plurality of sheets and reducing running costs.

An image forming apparatus is for sequentially ejecting a sheet S on which an image is formed and stacking the plurality of sheets to form a bundle of sheets, the image forming apparatus including waste toner adhesion means 11 for allowing waste toner T to be adhered on the sheet S during the sheet ejection, and heating and pressuring means 12, 13 for heating and pressuring a bundle of sheets formed by stacking a plurality of sheet S on which the waste toner T is adhered by the waste toner adhesion means 11 so that the sheets are adhered with the waste toner T therebetween. The waste toner adhesion means 11 allows the waste toner T to be adhered on the sheet S while the sheet S is moving during the sheet ejection.
