Conveying device and image forming apparatus

摘要

A conveying device includes a pair of first nipping rollers configured to be movable in a width direction while nipping a 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 a 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 pair of first nipping rollers is moved in the width direction based on a detection result of the detecting unit while the pair of first nipping rollers nips the recording medium so that a positional deviation of the recording medium in the width direction is corrected.

主权项

1. 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, androtate 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; and a controlling unit configured to correct lateral registration of the recording medium by controlling the conveying device to switch 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.
