摘要： PROBLEM TO BE SOLVED: To provide a paper ejecting device and an image forming device capable of preventing the occurrence of a jam and stacking failure, even if a curl is caused in a rear end part of a sheet.
SOLUTION: This image forming device 100 has a paper ejecting unit (a paper ejecting device) 180, and stacks the sheet 200 ejected from an ejecting port 61 on an inclined paper ejecting tray 1. A falling wall 2 rotating around a shaft 51 in response to pressure from the sheet 200 stacked on the paper ejecting tray 1, is erected in an end part of the paper ejecting tray 1. When the curled sheet is ejected from the ejecting port 61, a rear end part 200T abuts on the falling wall 2 in a state of floating a curled part from the paper ejecting tray 1. When a plurality of sheets 200 are stacked, the falling wall 2 rotates by weight of the sheets, and since the rear end part 200T separates from the ejecting port 61, the jam and the stacking failure are not caused. Since an inclination sensor 4A or an inclination sensor 4B detect that an inclination of the falling wall 2 becomes a threshold value or more, a full state of the curled sheet can be detected.

摘要： PROBLEM TO BE SOLVED: To prevent recording paper from winding around a roller even if the front and back surfaces of the recording paper are reversed by switchback conveyance, and the recording paper is subjected to both side printing. SOLUTION: Upon the printing of the front surface in recording paper, not only a void region B11 at the tip of the front surface of the recording paper, but also a void region B21 at the tail of the front surface is formed, and, upon the subsequent printing of the back face in the recording paper, a void region B22 at the tail of the back face in the recording paper is formed. Thus, upon the fixing of a toner image on the front surface of the recording paper, the void region B11 at the tip of the front surface in the recording paper is floated up from the circumferential face of a roller 35 in a fixing unit 27, and the end parts of the recording paper can be easily peeled by peeling pawls 37. Further, upon the fixing of a toner image in the back face, the void regions B21, 22 at the front surface and the back surface of the recording paper float up from the circumferential faces of the respective rollers 35, 36, and the edge parts of the recording paper can be easily peeled by the peeling pawls 37.

摘要： PROBLEM TO BE SOLVED: To provide a compact recording paper carrying device capable of preventing recording paper from being uselessly bent immediately before a resist roller without causing the deterioration of performance, a document feeding device, and an image forming apparatus including the devices.SOLUTION: The recording paper carrying device includes a resist roller and a transfer roller disposed adjacent to the resist roller and rotates the transfer roller (at a rotation speed Vp) to carry the recording paper so that a front edge thereof contacts with the resist roller in a stationary state (Vr=0) to cause the recording paper to form a prescribed bend. In this case, the device starts resist roller rotation to carry the recording paper by the resist roller at a time t4 when the transfer roller is rotating at a specific rotation speed (Vp=V1) and then accelerates the transfer roller rotation at a time t5 when the rotation speed Vr of the resist roller equals the specific rotation speed V1 of the transfer roller. In this way, the device prevents the recording paper from being uselessly bent immediately before the resist roller.
