Abstract: A sheet conveyance device includes a loading section, a sheet feeding unit, a separation section disposed downstream in a sheet conveyance direction from the sheet feeding unit, a conveyance member to transport a sheet separated by the separation section, a trailing-edge detector disposed at a first conveyance distance (L1) downstream from a separation position (Ab) and including a rotary follower and a rotation detector, a first leading-edge detector disposed downstream from the trailing-edge detector, and a controller. The trailing-edge detector A detects a sheet length in the sheet conveyance direction. The controller causes the sheet feeding unit to start sheet feeding in response to detection of the leading edge of the sheet by the first leading-edge detector when the detected sheet length equals a predetermined reference length and in other cases in response to detection of the trailing edge of the sheet by the trailing-edge detector.

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.
