Conveying device and image forming apparatus

A conveying device for conveying a recording medium along a conveying path, the conveying device comprising:

• a pair of first nipping rollers configured to
• be movable in a width direction while nipping the recording medium, and
• rotate to convey the recording medium;
• a pair of second nipping rollers configured to
• be movable in the width direction while nipping the recording medium, and
• rotate to convey the recording medium, the pair of second nipping rollers being arranged on an upstream side of the first nipping rollers in the conveying path;
• and
• a detecting unit configured to detect an amount of positional deviation in the width direction of the recording medium being conveyed in the conveying path,
• the conveying device is switched between a first operation and a second operation based on a thickness of the recording medium,
• in the first operation, the pair of first nipping rollers and the pair of second nipping rollers being moved in the width direction based on a detection result of the detecting unit while the pair of first nipping rollers and the pair of second nipping rollers nip the recording medium, so that a positional deviation of the recording medium in the width direction is corrected, and
• in the second operation, the pair of first nipping rollers is moved in the width direction is moved based on the detection result of the detecting unit while the pair of first nipping rollers nips the recording medium and the second nipping rollers are separated from each other, so that the positional deviation of the recording medium in the width direction is corrected.
