摘要： An optical scanning apparatus is constructed to detect one or more defective or damaged light emitting devices of a light source unit and forms images having substantially the same quality as that of the images formed when all of a plurality of light emitting devices of a light source of the apparatus are functioning normally even when any one of the plurality of light emitting devices are damaged or broken, without decreasing the image forming performance of the apparatus. The optical scanning apparatus detects one or more damaged or broken light emitting devices and then compensates for the light omitted due to the damaged or broken light emitting devices using the normally functioning light emitting devices without decreasing the image forming speed or quality of the optical scanning apparatus. In order to compensate for a defective light emitting device, the optical scanning apparatus uses various solutions such as increasing the rotating speed of the deflector while increasing the modulation speed of the light emitting devices by the same amount, increasing beam spot diameter in the subscanning direction, changing the output power of the light emitting devices on a surface to be scanned in order to increase beam spot diameter in the main scanning direction and the subscanning direction, and changing the focal length of the line image forming optical apparatus and increasing either the rotation speed of the deflector or the rotation speed of the surface to be scanned or photoconductive drum.

摘要： An optical scanner which performs optical scanning of a surface to be scanned by deflecting a luminous flux having a wavelength λ from a light source by means of an optical deflector, and condensing the deflected flux toward the surface to be scanned through a scanning image forming optical system, thereby forming an optical spot on the surface to be scanned. The scanning image forming optical system has at least one lens, and when the focal length fσ in the main scanning direction at a surface accuracy σi is defined as follows: fσ={2.6846 λ×√(k)×fm2/ω2}−fm where, fm represents the focal length in the main scanning direction of the scanning image forming optical system; k represents the number of lens surfaces; ω represents the aimed spot diameter of the optical spot in the main scanning direction at an image height of 0; σI represents the surface accuracy of the i-th lens surface as counted from the optical deflector side; n represents the refractive index of material of the lens having the i-th lens surface; and 1/l represents the spatial frequency in the main scanning direction on the lens surface; then, the surface accuracy σi, the focal length fσ, the refractive index n, and the spatial frequency 1/L satisfy, for each lens surface, the following condition: 0
