To provide a sheet conveying technique that can realize highly accurate skew correction with an inexpensive and simple apparatus configuration. A sheet conveying apparatus includes: first and second rollers that are arranged in positions different from each other in a direction orthogonal to a sheet conveying direction and can be driven to rotate independently from each other; a first skew detecting unit that is arranged on an upstream side or a downstream side of the first and second rollers in the sheet conveying direction and detects skew of a sheet at first skew detection accuracy; and a second skew detecting unit that is arranged further on the downstream side than the first skew detecting unit in the sheet conveying direction and detects skew of the sheet at second skew detection accuracy higher than the first skew detection accuracy. A skew amount of the sheet is determined on the basis of detection results of the respective first and second skew detecting units. To reduce the determined skew amount, the first and second rollers are driven to rotate independently from each other and convey the sheet.
