Abstract: A drive transmission device, which is included in an image forming apparatus, includes a drive transmission body to which a drive force is applied from a driving source, and a rotary shaft having a press-in portion mounted on one end thereof in the axial direction. The press-in portion has multiple planes disposed parallel to an axial direction and configured to receive the drive transmission body. The multiple planes include upstream and downstream side planes disposed downstream from the upstream side plane in a press-in direction of the drive transmission body. The upstream and downstream side planes are aligned along the press-in direction of the drive transmission body and have respective distances different from each other from an axial center of the rotary shaft. A distance from the downstream side plane to the axial center is greater than a distance from the upstream side plane to the axial center.

Abstract: An image forming apparatus includes an image forming unit, a paper loading base on which manual-feed paper is loaded, a manual-feed paper conveying unit, and a dustproof cover which covers the paper loading base being in the overhang state. The paper loading base has a lower end rotatably supported on one outer surface portion of the device main body, and is opened from an upper end thereof and disposed at a predetermined oblique angle or in a horizontal overhang state such that an overhang side becomes an upper side in an oblique direction. The manual-feed paper conveying unit is conveys the manual-feed paper on the paper loading base onto a paper conveyance path one by one. The dustproof cover includes a base which engages with the paper loading base, and an opening-and-closing cover which is rotatably connected to the base and is opened upwardly on the overhang side.

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.
