Abstract: A laser scanning device includes a rotary polygon mirror, a drive motor, a light detecting portion, a measurement processing portion, and an identification processing portion. The rotary polygon mirror has reflection surfaces and rotates such that light is scanned by the reflection surfaces in sequence. The light detecting portion detects the light scanned by the rotary polygon mirror. The measurement processing portion, in each of light detection cycles, measures an interval between a light detection timing and an output timing at which a drive signal that is to be input to a drive motor first after the detection timing, is output. The identification processing portion identifies a reflection surface corresponding to a standard interval, based on the standard interval and the measured interval, the standard interval being one of intervals acquired in the detection cycles that correspond to the reflection surfaces.

Abstract: In one embodiment, an image forming apparatus includes an image region dividing portion which determines, within an image formable width, an image boundary position that matches with one of matrix boundaries corresponding to boundaries between dither matrices, and sets image adjustment regions. The image forming apparatus also includes a correction processing portion which uses common calibration data to determine imaginary adjustment regions positioned closest to the image adjustment regions, respectively, in a main scanning direction, and uses a correction amount for the determined imaginary adjustment region to correct the position in a sub-scanning direction, thereby reducing a color shift. The image region dividing portion determines the image boundary position by applying a rounding function to a value obtained by dividing the number of pixels constituting a width of the image adjustment region by the number of pixels in one cycle of the dither matrix in the main scanning direction.

Abstract: An image forming apparatus performs a halftone process using plural dither matrices. Generated is calibration data to calculate a color registration error amount corresponding to a primary scanning directional position of an image forming available width. An image area dividing unit determines an image boundary position that is identical to any of matrix boundaries of plural dither matrices arranged in an image forming target area, and divides the image forming target area into plural image adjustment areas using the image boundary position. A correction processing unit corrects secondary scanning directional positions of the plural image adjustment areas, using respective correction amounts calculated with the calibration data. Further, the image area dividing unit determines the image boundary position using a remainder left by dividing in the primary scanning direction the number of pixels of the image adjustment area by the number of pixels of the dither matrix.

Abstract: An optical scanning device has an optical housing. A coupled Helmholtz resonator having a first resonance space and a second resonance space therein is disposed in the optical housing. A translucent partition wall, a first partition wall, and a second partition wall which extend from a bottom wall to a top wall of the optical housing are arranged in this order from an upstream side toward a downstream side on an optical path between a light source and a rotary polygonal mirror. The first and second resonance spaces are separated from each other by the three partition walls. One of the first and second resonance spaces resonates at a frequency of a rotational speed of a motor, and the other of the first and second resonance spaces resonates at a generated frequency of a wind noise generated by the rotary polygonal mirror.
