Abstract: An image forming apparatus includes an image bearing member, a transfer portion, first and second correcting portions including first and second roller pairs and first and second detectors, respectively. The first and second correcting portions correct a sheet position in a widthwise direction. A controller, in a case the sheet is fed to the transfer portion via the first correcting portion from the second correcting portion, causes the first correcting portion to correct the sheet position to a first position to be aligned with the image transferred in the transfer position and causes the second correcting portion to correct the sheet position to a second position. When the sheet has been moved to a reference position by the second roller pair, the second position is a position offset from the reference position toward an opposite side to a direction where the sheet position detected by the first detector is shifted from the first position.
