发明名称 Multicolor image forming method and apparatus therefor
摘要 A method of forming a multicolor image and an apparatus therefor capable of reducing the deviation between successive toner images of different colors and enhancing dot reproducibility. In the event of the second and successive sequences of steps included in a single multicolor image forming process, the intensity of a laser beam is controlled together with a beam diameter or an emission pulse width such that, when the laser beam scans part of the photoconductive element where a toner image formed by the preceding sequence of steps is present, the laser beam forms a dot of substantially the same size in both the part where a toner image is present and part where a toner image is absent, in matching relation to the interception and scattering characteristics of the laser beam due to the toner image.
