The pulse modulation mechanism performs a pulse modulation to input image data to output pulse-modulated image data. The laser light source generates a laser light beam according to the pulse-modulated image data. The laser light beam has a wavelength variation smaller than 2.0 nm per one pulse of the laser light beam. The light deflecting mechanism converts the laser light beam into a scanning laser light beam. The scan-imaging device condenses the scanning laser light beam into a scanning light spot on a surface to be scanned.

摘要： An optical scanning apparatus using an underfilled or overfilled optical system includes a number M of light sources, first, second, and third optical scanning lens systems, and a rotary polygon mirror. The number M of light sources emit a laser light beam. The first optical scanning lens system performs a coupling process to the laser light beam. The second optical scanning lens system collects light of the laser light beam in an approximately linear state extended in a main scanning direction. The rotary polygon mirror has a number N of deflective reflection surfaces for deflecting the laser light beam. The third optical scanning lens system gathers the laser light beam from the rotary polygon mirror to form a beam spot on an imaging surface. In this optical scanning apparatus, the predetermined number M satisfies a condition: 3×Rp/Rmax≧M≧Rp/Rmax, wherein Rp and Rmax are defined as: Rp≡(Dpi/25.4)×(260×Ppm)/N, and Rmax≡(5.4×106)×√{N16/(A4×t)}, respectively.

摘要： An optical scanning apparatus includes a light source for radiating a light beam, an optical scanning system for deflecting the light beam from the light source and condensing the light beam on a surface to be scanned, a detecting device for detecting an image forming state of the light beam scanned by the optical scanning system, and an adjusting mechanism for adjusting the focal position of the light beam on the surface to be scanned. The detecting device includes a very low cost detecting element that can accurately detect an image forming state of the light beam scanned by the optical scanning system independently in a main scanning direction and in a sub scanning direction. While the focal position of the light beam is changed continuously or at a predetermined pitch by the adjusting mechanism, the detecting device monitors the image forming state of the light beam and detects the location and vicinity of a light beam waist position relative to a desired position on the surface to be scanned.
