Abstract: 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.

Abstract: 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.
