Abstract:
A sheet conveying apparatus, an image forming apparatus, and an image reading apparatus are capable of stably correcting the delay or the advance of a sheet even if sheet conveying rollers such as a skew feeding correction roller and the like are decentered. The delay amount or the advance amount of the sheet being conveyed is detected by a deviation amount detection unit and a control amount setting unit sets the sheet conveying speed and the correction time of a sheet conveying roller which corrects the delay or the advance of the sheet based on the delay amount or the advance amount of the sheet detected by the deviation amount detection unit. The control amount setting unit sets the sheet conveying speed and the correction time of the sheet conveying roller so that the delay or the advance of the sheet is corrected when the sheet conveying roller rotates integer multiple.
