Abstract
To provide a sheet conveying apparatus capable of enhancing an accuracy of correcting a skew of a sheet, and of preventing position shift of a sheet. The present invention provides a sheet conveying apparatus for conveying a sheet by a sheet conveying unit disposed along a sheet conveying path, including: a skew detection sensor for detecting a skew of the sheet with respect to a sheet conveying direction by a plurality of detection sensors disposed in a direction intersecting perpendicularly the sheet conveying direction; and a skew correction roller adapted to be pivotally moved in a direction of correction of a skew of the sheet in a state with the skewed sheet being held on the basis of a detection signal from the skew detection sensor, in which one of the plurality of detection sensors of the skew detection sensor is disposed nearly on an extension line from a pivotal movement center of the skew correction roller in the sheet conveying direction.
