摘要： An optical scanning apparatus in which an exposing signal is generated from pattern data indicating a position to be exposed by a light beam on a surface-to-be-scanned. A corrected exposing signal is generated by varying the width of pulses of the exposing signal in accordance with a distance between an exposing area corresponding to the pulse and an optical axis of the scanning optical system. The light beam is emitted and modulated by the corrected exposing signal. The pulse width and/or the light quantity of the light beam is/are varied in accordance with the distance between the exposing area and the optical axis of the scanning optical system.

摘要： The apparatus is adapted to deflect a light beam from a laser light source for each of the color components by means of a deflection mirror surface which oscillates, thereby making the light beam reciprocally scan in a main scanning direction. In this apparatus, however, only a light beam SL which scans in a first direction (+X) of the main scanning direction is irradiated in an effective image region on a photosensitive member, so as to form a latent image thereon. The resultant latent image is developed to form a toner image. Since image formation is performed using only the light beam SL which scans in the first direction (+X), the images may be formed at the consistent density irrespective of the image types. Furthermore, the scanning directions of the light beams SL for all the color components are uniformly defined to be the first direction (+X), so that the toner images of the respective colors may maintain the consistent density.
