摘要： An optical scanning device includes a polygon mirror, a beam detector, a correcting unit, and a controller. The polygon mirror deflects and scans a light beam in a main scanning direction on a surface of an image carrier. The beam detector detects a beam position of the deflected light beam in a sub-scanning direction. The correcting unit calculates a correction amount of out-of-color registration based on the beam position, and corrects out-of-color registration in the sub-scanning direction based on the correction amount. The controller controls, during correction of out-of-color registration, a deflection speed of the deflector to be less than a deflection speed for writing a latent image on the surface of the image carrier.

Alternatively, when in detection mode, the control device controls the correction of color registration errors between each color forms color registration error detection patterns on a transfer member belt, sets the scan line from among the plurality of scan lines obtained by a pattern detection sensor for the color that passes through the lens that is most distant from the polygon mirror, as the standard scan line, and stores data for the standard scan line and bending correction values for the scan lines of other colors with respect to the standard scan line in the memory device. When forming images, the control device reads the data for the most distant standard scan line and the bending correction values for the scan lines of the other colors stored in the memory device, and carries out correction so that the laser irradiation position coincides with the standard scan line in accordance with the correction values via the sub scan deflecting element.

摘要： An image forming apparatus includes a plurality of image carriers and an optical writing device including light sources that emit light beams of different wavelengths, a deflector that deflects the light beams emitted from the light sources and synthesized on an identical axis in a sub-scanning direction, a first beam separator, a second beam separator, a first imaging device, and a second imaging device. The first beam separator and the second beam separator are located between the first imaging device and the second imaging device and transmit or reflect the light beams according to travel directions or wavelengths thereof. One of the targets is scanned with the light beam transmitted through the second beam separator. Another target is scanned with the light beam reflected by the second and first beam separators. The first and second imaging devices narrow the beams in the main scanning direction and the sub-scanning direction, respectively.
