Patent ID: 7626722

Claim:
An image recording apparatus, comprising: a light emitting source including a plurality of light emitting units that emit a plurality of laser beams, the light emitting units being arranged at predetermined intervals; a rotating deflector that, while rotating, deflects the plurality of laser beams to scan in a main scan direction; a photoconductor having a scanning surface irradiated by the laser beams deflected by the rotating deflector, each laser beam forming an image dot on the scanning surface; and a detection unit arranged to detect the laser beams and measure intervals of the laser beams in the main scan direction, each of the intervals being a distance between an image dot formed on the scanning surface by one laser beam and another image dot formed on the scanning surface by another laser beam; wherein light emission timings of the light emitting units are adjusted in response to the measured intervals to compensate for interval differences of the light emitting units.
