Abstract
When continuous-conveying control is executed in a conveying apparatus which can handle various sizes of sheet, a conveying apparatus which can efficiently detect a conveying error by a required minimum conveyed amount or conveying time according to a sheet size is provided. For that purpose, a maximum conveyed amount from start of sheet feeding of the subsequent page to determination to be a sheet-feeding error is set based on a detection result of a rear end portion on a previous page by a PE sensor. The maximum conveyed amount when the rear end portion of the previous page is detected is set smaller than the maximum conveyed amount when not detected.
