    摘要： A sheet conveying device (26), which is incorporated in an image forming apparatus, includes a sheet holding and conveying roller pair (48) to convey a sheet (20) while holding the sheet (20) at a nip (N), and a gate member (64) disposed movable with rotation of the sheet holding and conveying roller pair (48) to correct skew of the sheet (20) in a sheet conveying direction while a leading end of the sheet (20) in the sheet conveying direction abuts against the gate member (64). The gate member (64) has a contact surface (64a) against which the sheet (20) abuts. The contact surface (64a) is disposed upstream from the nip (N) of the sheet holding and conveying roller pair (48) in the sheet conveying direction. A setting position of the contact surface (64a) is adjusted according to thickness of the sheet (20).

    摘要： The present invention provides a recording apparatus comprising convey means for conveying a sheet in a predetermined convey direction, a pair of rollers arranged downstream of the convey means in the convey direction for conveying the sheet in the convey direction or in an opposite direction by their rotations in a normal direction or in a reverse direction, and control means for controlling the convey means and the pair of rollers. Control means control them in such a manner that, after the sheet conveyed by the convey means is conveyed in the convey direction by a predetermined amount by the pair of rollers, the pair of rollers are rotated in the reverse direction while applying a conveying force in the convey direction to the sheet by the convey means, thereby conveying the sheet in the opposite direction until the sheet passes through a nip between the pair of rollers.

    摘要： An image-forming apparatus (100) contains an image-forming portion (10), a first conveying portion (200) that is arranged at an upstream side of the image-forming portion (10) along a sheet conveying direction, a second conveying portion (300) that is arranged at an upstream side of the first conveying portion (200) along the sheet conveying direction and a control portion (50). The control portion (50) controls the first conveying portion (200) to move a pair of registration rollers (210) along a direction that is orthogonal to the sheet conveying direction while the pair of registration rollers (210) nips the sheet when conveying the sheet to the image-forming portion (10). The control portion (50) controls the second conveying portion (300) to move one of the pair of conveying rollers (310) along the direction that is orthogonal to the sheet conveying direction while the pair of conveying rollers does not nip the sheet.
