Abstract
A multibeam scanning apparatus includes a polygon mirror provided between laser beam generation sources and a photosensitive drum of a target, for deflecting laser beams emitted from the laser beam generation sources to scan the photosensitive drum, galvanomirrors provided between the polygon mirror and each of the laser beam generation sources, for allowing a radiating position of each of the laser beams to move on the photosensitive drum, a sensor located in a downstream position of the polygon mirror and optically in conjugation with the photosensitive drum, for sensing the radiating positions of the laser beams on the photosensitive drum, and controller for controlling the galvanomirrors in order to set the radiating positions of the laser beams on the photosensitive drum in response to a signal output from the sensor.
