    摘要： A drive transmitter includes a first unit including a coupling portion having grooves spaced at an angle of 180 degrees in the rotational direction, and a second unit having projections spaced at an angle of 180 degrees in the rotational direction. The projections are configured to be inserted into the grooves of the coupling portion. The coupling portion has a guiding portion and a non-guiding portion. The guiding portion is sloped, with a height from a bottom face of the grooves decreasing in the rotational direction of the first unit, and is configured to guide the projections to the grooves. The non-guiding portion is disposed at a point symmetrical position to the guiding portion to an axial center of the first unit. One of the projections is not in contact with the non-guiding portion while another one of the projections is in contact with the guiding portion.

    摘要： A sheet adjusting device applicable to a sheet holding receptacle, an image forming mechanism, and an image reading mechanism includes a sheet setting plate to place a sheet thereon; first and second regulating member to slidably move in a given direction, and a friction-reducing unit disposed on the sheet setting plate to reduce a frictional force on an underside of the sheet. Alternatively, a sheet adjusting device includes a sheet setting plate, a sheet contact face disposed downstream of the sheet setting plate to cause the leading edge of the sheet abuts against the sheet contact face, first and second regulating member, and a friction-reducing unit disposed on the sheet contact face to reduce a frictional force on the sheet contact face and the leading edge of the sheet.

    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.
