Paper discharging apparatus, paper discharging method, image forming apparatus and image forming method

An image forming method for forming image by an image forming apparatus which includes a paper conveyance path;

• a first conveying unit configured to convey a paper along the paper conveyance path;
• a second conveying unit including a pinch roller and a feeding roller that are arranged closer to a downstream side of a paper conveying direction than the first conveying unit, the pinch roller and the feeding roller clamping the paper therebetween and conveying the paper along the paper conveyance path;
• a printer unit configured to print on the paper;
• and a movable mechanism, including a surface part having a specified shape, moving the surface part between a first position that the surface part is not contacted with the pinch roller and a second position that the surface part is contacted with the pinch roller through the paper and pushes the pinch roller until the pinch roller is separated from the feeding roller and a control unit that controls the moveable mechanism;
• the forming method, comprising:
• moving the surface part to the second position by the movable mechanism controlled by the control unit to clamp the paper by the pinch roller and the surface part,
• bending the paper through conveying the paper by the first conveying unit, then moving the surface part to the first position by the movable mechanism controlled by the control unit to clamp the paper by the pinch roller and the feeding roller,
• discharging the paper from the conveyance path by rotating the feeding roller,
• moving the surface part to the first position by the movable mechanism controlled by the control unit and clamping the paper by the pinch roller and the feeding roller after the paper is printed by the printer unit and cut by the cutter, and
• discharging the paper from the conveyance path by rotating the feeding roller.
