摘要： A sheet container includes a bottom plate, a regulating body, and a holding body. The bottom plate is disposed movable and has a bottom plate-side contact portion. The regulating body regulates a position of a trailing end of a sheet. The holding body has a holding body-side contact portion and to hold the regulating body. The bottom plate and the holding body have a gap between the bottom plate-side contact portion of the bottom plate and the holding body-side contact portion of the holding body in a state in which the bottom plate is not rotated. The bottom plate-side contact portion of the bottom plate and the holding body-side contact portion of the holding body contact with each other along with rotation of the bottom plate.

摘要： An image forming apparatus includes a sheet container accommodating a recording medium therein, a sheet separating feeder including a sheet feeding body and a sheet separating body, an image forming part, and a bend applier. The sheet feeding body feeds the recording medium along with a surface movement thereof while the recording medium contacting the surface thereof. The sheet separating body forms a sheet separation nip region with the sheet feeding body and sandwiches the recording medium in the sheet separation nip region. The sheet separating feeder separates and feeds the recording medium contacting the sheet feeding body. The image forming part forms an image on the recording medium. The bend applier having a leading end of an elastic material contacts and bends the recording medium before the sheet separation nip region and generates a wrinkle extending on the recording medium in a sheet conveying direction.

摘要： A sheet feeder, which is included in an image forming apparatus, includes a sheet bypass member openably closable to one side surface of a body of the image forming apparatus, a pickup roller to feed and convey a sheet loaded on the sheet bypass member, and an arm to hold the pickup roller and to open and close with the pickup roller. The arm includes a contact portion extending in a shape of projection toward an upstream side from the pickup roller in a sheet conveying direction of the sheet bypass member. As the sheet bypass member is rotated upward to be closed and stored to the side surface of the body, the contact portion of the arm contacts the sheet bypass member to rotate the arm upward to cause the sheet bypass member to approach to the side surface of the body.

摘要： A sheet positioning device includes a sheet setting plate, first and second regulating members disposed facing each other to move in an orthogonal direction to a sheet conveyance direction to regulate positions of two facing ends of the sheet on the plate by contacting these ends, a driving mechanism to move the first regulating member in the orthogonal direction, first and second contact detectors mounted on the first and second regulating members to detect contact of the two facing ends, and a controller to stop the driving mechanism based on detection results obtained by the first and second contact detectors. The first and second regulating members are used to adjust a position of the sheet to a predetermined position. Respective contact surfaces of the first and second contact detectors with the sheet extend over an entire maximum loadable range in a sheet setting direction on the plate.
