    摘要: A multi-beam scanning device includes a plurality of light sources which emit multiple beams. A plurality of coupling lenses couple the multiple beams from the light sources. A converging lens device converts the coupled beams into converging beams, the converging beams being elongated in a direction corresponding to a main scanning direction and converging only in a direction corresponding to a sub-scanning direction, at least two of the converging beams forming a difference angle therebetween. A rotary deflector has a reflection surface rotated about a fixed rotation axis. The reflection surface deflects the converging beams while the reflection surface is rotated. A scanning lens device scans an image surface in the main scanning direction at a substantially uniform velocity by focusing each deflected beam into a beam spot on the image surface. The multi-beam scanning device is configured to satisfy desired conditions to allow the multi-beam scanning device to achieve excellent optical characteristics without using a polarization beam splitter. Further, an image forming system and method which uses such a multi-beam scanning device is provided.

    摘要: A multi-beam scanning apparatus performs image scanning by emitting multiple beams from a plurality of light sources, which beams are deflected by a common deflector at equiangular velocity. The beams are then condensed by a common scanning image forming lens so as to form optical spots on a scanning surface. As a result, the plurality of lines are simultaneously scanned by the beams on the scanning surface at a substantially constant velocity. Characteristics of the light sources, such as the wavelength thereof, and other factors such as writing density and desired writing width of a writing line, are arranged to eliminate differences in a written vertical line in a sub scanning direction caused by a magnification difference, regardless of the cause of such differences. In addition, the modulation frequency of the plurality of light sources is made different from each other so that writing widths of the dots written by the plurality of light sources become the same.
