摘要： An image forming apparatus includes an optical scanning system that simultaneously forms a group of two scanning lines extending in a main scanning direction on a surface of a photoconductive member at a prescribed scan line interval in a sub scanning direction. An exposure intensity distribution changing device is provided to symmetrically change exposure intensity distribution of two scanning lines in the main scan direction. A group of two scanning lines formed next on the photoconductive member partially overlaps with the group previously formed with displacement of a prescribed feed pitch in the sub scanning direction so that a prescribed numbers of the two scanning lines neighboring to each other of the different groups are paired to form a prescribed number of combination scan lines. The exposure intensity distribution changing device substantially equalizes the sum of the exposure intensity of the pair of neighboring scan lines of the combination scan line at every section in the main scanning direction.

摘要： The invention aims at provision of an optical scanner in which an optics required for equalizing an optical magnification in a scanning range is produced with high accuracy, so that intervals among a plurality of scanning lines on a to-be-scanned surface are even in the scanning range. The scanning optics includes a refraction surface and a reflection surface whose sub-scanning-direction curvature radii vary continuously. The reflection surface is disposed on the to-be-scanned surface side of the refraction surface. The curvature radius of the reflection surface varies symmetrically with respect to the optical axis, and the curvature radius of the refraction surface varies asymmetrically with respect to the optical axis.

摘要： A multi-beam image forming apparatus includes: first and second semiconductor laser arrays each having n laser elements; a multi-beam generation unit that generates 2n laser beams by synthesizing laser beams generated by the first and second semiconductor laser arrays; a beam detection unit that generates synchronous detection signals to obtain synchronous scanning of the respective laser beams; and a control unit. The beam detection unit includes first and second beam detection units disposed substantially at a same position in a main scanning direction and adjacently disposed in a sub-scanning direction. The n laser beams of the first and second semiconductor laser arrays are detected by the first and second beam detection unit, respectively. The control unit controls image formation start positions of the 2n laser beams on the basis of the synchronous detection signals output from the first and the second beam detection units.

摘要： In an optical scanning apparatus, a scanning lens is composed of three lens elements. The centrally located lens element of the scanning lens has a refractive power in the direction for correcting the surface tilt, that is, an inverted number of a focal length that is changed in accordance with the scanning view angle, whereby curvature of field is well corrected and RMS spot diameters on the scanning surface may be small. In addition, even if the view angle is increased, imaging characteristics may be kept at a high resolving power.

摘要： A beam deflector device in which two light beams from two light sources are simultaneously applied through movable reflectors to a beam deflector scanning a drum. The beams are also applied, through a beam splitter to two photodetectors used to control the position of the respective reflector. The two beams are separated before they are applied to the photodetectors by means of polarization plates, color filters, diffraction gratings or prisms.
