摘要： An optical scanning device acquires a displacement amount of each of scanning light beams in the main scanning direction, and corrects, based on the displacement amount, writing energy density at a write position such that a variation in image density due to a variation of the displacement amount is reduced. The light beams are used for scanning a target surface to write image data on the target surface. The writing energy density is an amount of light per unit surface area of the target surface.

摘要： A light source unit is disclosed. The light source unit includes a phase type optical element which modulates a phase distribution of laser beams emitted from a light source. The phase type optical element has a phase distribution so that a first ratio of the peak intensity of side lobe laser beams to the peak intensity of main lobe laser beams in a beam intensity profile at a focal position of the laser beam condensing element is greater than a second ratio of the peak intensity of side lobe laser beams to the peak intensity of main lobe laser beams in the beam intensity profile at the focal position of the laser beam condensing element when it is assumed that the phase type optical element is not disposed.

摘要： An optical scanner includes a light source modulated based on image data, an optical deflection and scanning part deflecting a light beam emitted from the light source, and a scanning and imaging optical system condensing the deflected light beam toward a scanning surface so as to form a light spot optically scanning the scanning surface. The effective scanning region of the scanning surface is divided into a plurality of regions according to a scanning line curving characteristic. Suitable image data for optically scanning the divided regions are selected from image data of a plurality of image lines every time the light spot optically scans the effective scanning region, so that the image data of each of the image lines is written with scanning line curving being corrected.
