Sheet conveying apparatus and image forming apparatus

The object of the present invention is to provide a sheet conveying apparatus capable of correcting the skew conveying of a sheet without causing a tugging. In order to accomplish the object, the sheet conveying apparatus includes a detection unit for detecting an inclination to a sheet conveying direction of a sheet to be conveyed; an inclination correction unit for correcting the inclination of the sheet by rotating in a state of nipping the sheet of an inclined state based on a detection signal from the detection unit; a first conveying unit, which is provided in the upstream side of the inclination correction unit and nips the sheet toward the inclination correction unit and conveys the same; a first nipping release unit for releasing a nipping state of the second sheet conveying unit, which is provided in the downstream side of the inclination correction unit and nips the sheet from the inclination correction unit and convey the same to the downstream side; a second nipping release unit for releasing the nipping state of the second sheet conveying unit; and a control unit for controlling the first nipping release unit and the second nipping release unit to selectively release the sheet nipping state of the first sheet conveying unit and the second sheet conveying unit according to an inclination correction operation by the inclination correction unit.
