摘要： In an optical scanner, when an emission control unit varies a period at which image data is output from an output buffer of the emission control unit in order to correct a sub scan magnification of a LED array and a vacant region of an input buffer of the emission control unit ceases to exist, a buffer control unit temporarily stores the image data in a vacant region of a memory of an image correcting unit, and transfers the image data temporarily stored in the memory to the input buffer when the vacant region is generated in the input buffer.

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.

摘要： To print on the front side, image data saved in an image memory is read pixel by pixel along a main scanning direction x. Correction data for each block of pixels then is referred to, and the image data is read while being shifted in a sub-scanning direction y by a value of the correction data and is inputted to an exposing device. To print on the rear side, upon reading image data along the main scanning direction x, the image data in the image memory is read along the main scanning direction from a side opposite the one read at the time of printing on the front side. Positive and negative signs of deviation amounts specified by the correction data are reversed and the positions of the pixels to be read are shifted successively in a sub-scanning direction opposite to the one used while printing on the front side.

摘要： This invention makes it possible to prevent any uneven density and degradation in resolution in reciprocal laser scanning using a movable mirror. An image forming apparatus forms an image on a photosensitive member by scanning the photosensitive member with a laser beam reflected by a movable mirror with reciprocating the movable mirror whose rotation angle is changeable in accordance with an electrical signal. The apparatus detects the rotation direction of the movable mirror, and weights, on the basis of the rotation direction, image data of two lines along the sub-scanning direction in correspondence with the ratio of the scanning length after the start of laser write for a line of laser scanning to compensate the image to be formed using the movable mirror.

摘要： A scanning system is adapted to scan an image beam across a photoconductive surface. The scanning system includes an oscillating mirror and is operable to generate an image beam and to reflect the image beam off the oscillating mirror to bidirectionally scan the image beam across the photoconductive surface and thereby discharge regions on the surface. The system is further operable to dynamically scale an intensity of the image beam as a function of a position of the image beam on the photoconductive surface.

摘要： A light scanning device includes a polygon mirror configured to be rotatable around a rotation axis to reflect and deflect a light beam with a plurality of reflecting surfaces, a light source that makes a light beam incident onto the polygon mirror from an outside of a scanning range of the light beam being scanned in a main scanning direction by the polygon mirror, and an image forming optical system that converges the deflected light beam as a spot scanned in the main scanning direction on a scanned surface. In a state where the light beam is directed to a center of the scanning range on the scanned surface, a chief ray of the light beam intersects with a reflecting surface at a point shifted by a predetermined amount in a direction toward a side opposite the light source front a center of the reflecting surface in the main scanning direction.
