摘要： A pixel clock generator includes a frequency divider 4 that generates a pixel clock PCLK based on a high frequency clock VCLK, a comparator 5 that calculates an error Lerr in the time obtained by integrating a cycle of the pixel clock PCLK for a target number RefN from a time when synchronization signals SPSYNC and EPSYNC are detected, a filter 6, and a frequency calculating unit 7 that sets a frequency dividing value M of the frequency divider 4. The filter 6 and the frequency calculating unit 7 calculate an average of a frequency of the pixel clock PCLK based on the error Lerr, determine a reference error value from the error Lerr in N-cycles, calculate offset values of the frequencies of N pieces of pixel clocks PCLK based on a difference between the reference error value and the error Lerr, and calculate the frequency dividing value M based on a result obtained by adding the circularly selected offset values and the average of the frequency of the pixel clock PCLK.

摘要： An optical scanning device includes a scanning member (62), a plurality of light sources (611A-614A), a first reflection mirror (75), and a second reflection mirror (76). The scanning member (62) scans incident laser beams in a predetermined main scanning direction. The plurality of light sources (611A-614A) emit the laser beams from positions that are different along a sub scanning direction that is perpendicular to an optical axis direction of the laser beams and the main scanning direction. The first reflection mirror (75) is inclined around the main scanning direction as a rotation axis, is inclined around the sub scanning direction as another rotation axis, and reflects the laser beams emitted from the light sources (611A-614A). The second reflection mirror (76) is inclined around the main scanning direction as a rotation axis, is inclined around the sub scanning direction as another rotation axis, and reflects the laser beams reflected by the first reflection mirror (75) toward the scanning member (62).

摘要： In an image forming apparatus that forms an electrostatic latent image for detection on a photosensitive member by light irradiation and performs color-misregistration correction control on the basis of detection of a change in detection current due to the detecting electrostatic latent image passing through a processing unit disposed close to the periphery of the photosensitive member, the intensity of at least one of the apply voltage of the processing unit and the output of the light irradiation unit is set higher than that during normal image formation.

摘要： An image forming apparatus (1000) that suppresses occurrence of color shift in images transferred from image bearing members (100Y, 100M, 100C, 100K) onto an intermediate transfer member (108). A surface of each of a first photosensitive drum (100Y) and second photosensitive drums (100M, 100C, 100K) is charged. An exposure device (101Y, 101M, 101C, 101K), provided for each photosensitive drum, forms an electrostatic latent image by exposing an associated one of the charged photosensitive drums. A developing device, provided for each photosensitive drum, develops the electrostatic latent image with toner. An intermediate transfer belt friction-drives the photosensitive drums for rotation and has the developed images transferred thereon. Timing for exposing the second photosensitive drums is controlled based on a first surface distance (Ly) from an exposure light irradiated position to a primary transfer position of the first photosensitive drum, and a second surface distance (Dym, Dyc, Dyk) from an exposure light irradiated position of each second photosensitive drum to a primary transfer position thereof.

摘要： In a control apparatus, first type binary image data representing density of pixels arranged along a first image direction at a first resolution is acquired, and a first determining process is executed to determine an exposure pattern used to execute exposures of exposure lines at a second resolution lower than the first resolution along a first exposure direction. In the first determining process, a partial exposure pattern for exposing an output partial area that is correlated with a binary partial area and that overlaps N successive exposure lines is determined such that distribution of exposure amounts in the output partial area along the first exposure direction differs according to layout of second-value pixels in the binary partial area at least in the first image direction, thereby enabling an image of color material to be formed through development at a resolution higher than the second resolution in the first exposure direction.
