ABSTRACT:
A discharge device is usable for an image forming apparatus including a fixing portion having a heating roller in the shape of a hyperboloid for fixing a toner image formed on an envelope having a turned-up portion, and a stacking portion for stacking envelopes. The discharge device provided with a discharge roller system provided between the fixing portion and the stacking portion to discharge the envelope to the stacking portion has a upright portion provided near the discharge roller system below the transport path of the envelope to prevent the turned-up portion of the envelope from warping downward. This discharge device prevents a discharging envelope from coming into contact or colliding with the uppermost one of a stack of already discharged envelopes on the stacking portion, and enables the envelopes to be discharged suitably and to be stacked orderly on the stacking portion and increases an amount of envelopes stacked on the stacking portion.
