An image forming apparatus includes an image former, a conveyance path, a flipping conveyance path, a conveying mechanism and a hardware processor. The flipping conveyance path includes a side path connecting a first branch point in a downstream of the conveyance path to a junction in an upstream of the conveyance path and a re-feeding path connecting a second branch point in the side path to a re-feeding point in an upstream of the conveyance path. The hardware processor controls the conveying mechanism to perform (i) a conveyance operation to convey the sheet along the conveyance path, (ii) a draw-in operation to draw the sheet with the image into the side path, and (iii) a re-feeding operation to convey the sheet in a reverse direction to re-feed the flipped sheet from the re-feeding point to the conveyance path.
