Abstract: In image forming apparatuses producing recycled toner from residual toner and recycling the recycled toner, the toner composition changes, and the toner properties worsen, because the external additive contained in the collected residual toner that is collected with a cleaning portion (6) decreases during the image formation. The residual toner that has been collected with the cleaning portion (6) is conveyed through a conveyance path (51) to a collected residual toner storage (62), and external additive is supplemented from an external additive cartridge (64), and mixed with being stirred to produce recycled toner. In a fresh toner storage (63), fresh toner end recycled toner are stirred, and when the amount of toner in a developing portion (4) drops below a predetermined amount, toner is conveyed from the fresh toner storage (63) through a conveyance path (68) to the developing portion (4). The toner that has been conveyed to the developing portion (4) is supplied to a photosensitive drum (1).
