    Abstract: When fixing images onto normal sheets of paper, the pressing force between a pressing roller and a thermal roller of a fixing unit is designated by the urging force of only a first spring. On the other hand, when fixing images onto thick sheets, the pressing force is designated by the urging force of the first spring and the urging force of a second spring, which operates against the urging force of the first spring.

    Abstract: A sheet feeding apparatus has a plurality of sheet containers, a plurality of sheet feeding units and a plurality of curving conveying routes for guiding the sheets to a common conveying route. One of the sheet containers is adapted to hold envelopes and other sheets of high rigidity, and the sheet feeding apparatus is constructed such that a radius of curvature of the curving conveying route for the envelope and other sheets of high rigidity is made larger than a radius of curvature of a second curving portion of another conveying route.

    Abstract: Envelopes (9) are fed flap first and flap closed long dimension first into the nip of fixing rollers (3,4). The fixing rollers are less wide than the envelopes, and the printing system does not print on the edge of the envelope which is not fixed. Since this adds very little to the apparatus and software, wrinkle-free envelope printing is achieved at very low initial and overall cost.

    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.
