Abstract
An image forming apparatus includes an image transfer unit disposed along a sheet feed path. A sheet feed roller feeds a sheet toward an image transfer position where an image can be transferred by the image transfer unit. A sheet detect unit detects the sheet fed by the sheet feed roller and a control unit controls the rotational operation of the sheet feed roller in accordance with a detection result of the sheet detect unit. As such, a sheet feed path length, which extends between the image transfer position and a detection position where the sheet is detected by the sheet detect unit, is set at an integer multiple of a circumferential length of the sheet feed roller.
