ABSTRACT:
In a laser printer capable of printing on both sides of a sheet, alignment or skew of the sheet is corrected with register rollers before printing is performed first on a side of the sheet. The sheet with an image having been formed by a process unit is fed to a re-circulation path for printing on the other side of the sheet. The sheet alignment or skew is corrected in the re-circulation path by a guide plate while the sheet is fed by re-circulation feed rollers. The sheet fed back to the register rollers is fed toward the process unit without being temporarily stopped at the register rollers before printing on the other side of the sheet.
