Abstract
A laser beam printer includes: a recording medium for forming an image; a scanning unit for scanning a beam modulated by an image signal on the recording medium; a beam detector for detecting the position of the beam scanned by the scanning unit and outputting a synchro signal which defines the record start position on the recording medium; a sheet position detector for detecting the position, in the direction of scanning the beam, of a sheet to which the image formed on the recording medium is transferred; and a controller for controlling the output timing of the synchro signal in accordance with the position of a sheet detected by the sheet position detector.
