Sheet conveying device and image forming apparatus

A sheet conveying device comprising:

• a sheet detection unit disposed in a sheet conveying path, so as to detect skew of a conveyed sheet with respect to a sheet conveying direction, and to detect a positional displacement amount of the sheet in a sheet width direction perpendicular to the sheet conveying direction;
• and
• a position adjusting mechanism disposed in the sheet conveying path on a downstream side of the sheet detection unit in the sheet conveying direction, and configured to perform skew correction to correct the skew of the sheet, and to perform positional displacement correction to correct the positional displacement of the sheet on the basis of a detection result of the sheet detection unit, while conveying the sheet, wherein
• the position adjusting mechanism includes an adjusting roller pair configured to nip and convey the sheet, a skew correction motor configured to tilt rotation shafts of the adjusting roller pair with respect to the sheet conveying direction, and a positional displacement correction motor configured to move the adjusting roller pair in the sheet width direction,
• the sheet conveying path includes a first conveying roller pair disposed on an upstream side of the position adjusting mechanism in the sheet conveying direction, and a curved part disposed between the adjusting roller pair and the first conveying roller pair, the curved part curving in an S shape in a front and back side direction of the sheet, and
• the adjusting roller pair nips and conveys the sheet together with the first conveying roller pair.
