Abstract
Disclosed a multicolor image forming apparatus that facilitates correction operations to correct skews of a plurality of images. Turing a dial of an adjusting apparatus tilts a cylindrical mirror and thereby changes an irradiation position of a light beam to be irradiated onto a photoreceptor. Since the rotation of the dial and the movement of the cylindrical mirror correspond, an operator can know the state of the cylindrical mirror by visually checking a mark of the dial and a scale plate. When a color skew of images occurs, the operator can perform easily adjustment operations by the adjusting apparatus while checking a color skew amount and the state of a corresponding cylindrical mirror by the mark and the scale plate.
Claims11
A multicolor image forming apparatus for obtaining a multicolor image by overlapping images of a plurality of different colors formed on a plurality of photoreceptors by a plurality of light beams, the multicolor image forming apparatus comprising:
- optical members provided for each of said plurality of light beams;
- and correction units, provided corresponding to each of said optical members, capable of moving said optical members to move irradiation positions of said light beams to be irradiated onto said photoreceptors, wherein said correction units can be adjusted by setting units that obtain a movement amount of said optical members, relative to a reference value.
