摘要： An optical scanning device of the present invention includes a simple scanning lens. At least one of opposite surfaces of the lens has a nonarcuate shape, as seen in a polarization plane. At least one of the opposite surfaces is a special toric surface. Further, in a plane perpendicular to the polarization plane, the lens has a meniscus shape concave toward a polarizer. With this configuration, the lens achieves a desirable uniform velocity scanning capability and a desirable field curvature in the main scanning direction. The lens is therefore free from errors in configuration ascribable to molding while reducing the limitation on the tolerance of optical elements in the optical axis direction as to assembly.

摘要： An optical scanning device includes a single scanning lens. At least one of opposite surfaces of the lens has a nonarcuate shape, as seen in a polarization plane. At least one of the opposite surfaces is a special toric surface. Further, in a plane perpendicular to the deflection plane, the lens has a meniscus shape and has the concave surface facing toward a deflector. With this configuration, the lens achieves a desirable uniform velocity scanning capability and a desirable field curvature in the main scanning direction. The lens is therefore free from errors in configuration ascribable to molding while reducing the limitation on the tolerance of optical elements in the optical axis direction as to assembly.

摘要： An image forming system utilizing a light emitting diode (LED array) having LEDs arranged along a curved line. The LEDs are either edge emitting type LEDs or surface emitting type LEDs. The LEDs of the LED array emit light towards a center or optical axis of the lens. A plurality of lenses are connected together to form a lens array. Alternatively, two lens arrays can be utilized. If two lens arrays are utilized, each of the lenses in the lens array includes an aspherical surface. The curved LED array prevents the flaring of light and produces an even pattern of light emission on a light receiving surface such as a photoconductive drum.

摘要： An optical scanner is capable of effectively correcting a difference with respect to the sub-scanning direction between the positions of optical spots for scanning photoconductor drums of a tandem type color image forming apparatus. The optical scanner includes an optical axis adjusting part. The optical axis adjusting part uses a deflecting mirror or a wedge-shaped prism to deflect the optical axis of an optical beam with respect to the sub-scanning direction. As a result, it is possible to accurately correct a resist difference among individual image forming stations and form a high-quality color image without any color displacement.

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： In an optical scanning device, when pixel density is taken to be n, number of the light beams is taken to be b, and number of the deflection surfaces of a deflecting unit is taken to be p, a spatial frequency S denoted by S=1/(1/(25.4/n×b×p) is within a range of a spatial frequency characteristic for a visual perception system of a high relative luminous efficiency. When spacing between ends in a sub-scanning direction of a scanning line formed by one scan by the deflection unit is taken to be L1, and spacing between all progressive scanning lines at the surface to be scanned is taken to be L2, then L1>(k−1)×L2 is satisfied, where k is a total number of light emitting points of a light source.
