摘要： 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.

摘要： A copy item transport device is used in an image forming apparatus having an image bearing member and a pair of registration rollers before the image bearing member, and includes a separator for regulating multiple copy items to one copy item for each image formation. The separator is constructed by a forward roller being driven in a forward direction of transporting the copy item to the registration roller pair, a reverse roller in contact with the forward roller. The reverse roller is driven in a reverse direction of transporting the copy item backward, but rotatable in the forward direction together with the forward roller when receiving a greater transmitted forward torque from the forward roller than the reverse torque. The reverse drive to the reverse roller is stopped at the same time or after the forward drive to the forward roller is stopped to assure the nip of copy item by the registration roller pair.
