Abstract
PURPOSE: To provide a printer, which can measure the intensity of a laser beam easily for each scan by arranging a laser beam detector on the scanning line outside of the effective area in the vicinity of a photosensitive drum.
CONSTITUTION: The laser beam having been optically modulated in response to recording signals is reflected by a rotary mirror 3 to scan a photosensitive drum along a generation line. If a laser beam detector 6 is arranged in the vicinity of the drum 2 at the opposite side of a position, where a scan initiating optical detector 4 for synchronism with the scan, and at the scan terminal point of the scanning line outside of the effective scanning region, the intensity of the laser beam can be easily detected for each scan. As a result, a recorder can be maintained, inspected and adjusted to a satisfactory extent.
