A line head is provided with a plurality of organic-EL photo emitters, arrayed in a second direction perpendicular to the first direction to form a plurality of photo emitter arrays arranged in the first direction. A plurality of imaging lenses are arrayed in the second direction to form at least one lens array, so that an array of pixels defined on the photosensitive member are subjected to multiple exposure to light emitted from the photo emitter arrays in accordance with the movement of the photosensitive member, thereby forming an electrostatic latent image on the photosensitive member. At least one chromatic-aberration correcting lens is adapted to correct chromatic aberration of the imaging lenses relative to the first direction, and disposed between the photo emitter arrays and the lens array.

    摘要: An optical scanning device 65 is adapted to bring a deflector mirror plane 651 into independent pivotal motions about a first axis and a second axis perpendicular to each other. A mirror driver section including a first axis driver and a second axis driver is so controlled as to bring the deflector mirror plane 651 into pivotal motion about the first axis thereby deflecting a light beam L for scanning along a main scan direction. On the other hand, the deflector mirror plane 651 is pivotally moved about the second axis thereby to adjust the scanned beam L for its position on a photosensitive member 2 with respect to a subscan direction. Thus, even if the scanned beam is deviated from a reference scan position with respect to the subscan direction due to component tolerances or assembly errors, such a deviation can be corrected.
