摘要： In an overlapping head including a plurality of recording head chips overlapped to each other, a color shift can occur between a color recorded by an overlapping region and a color recorded by a non-overlapping region, which cannot be corrected by a density correction using head shading or the like. To correct such a color shift, a test pattern is recorded by the overlapping region and the non-overlapping region and colors of the recorded test pattern are measured. Color correction data to be used in correction of colors of an image to be recorded is generated based on a result of the measurement of the colors.

摘要： A printing apparatus performs printing on a printing medium by moving a print head relative to the printing medium in a main scanning direction, which is a width direction of the printing medium, and a sub-scanning direction that intersects the main scanning direction. The printing apparatus includes a print head that includes a plurality of nozzles configured to eject ink; an acquisition unit that acquires image data; and a dot forming unit that controls the print head so as to eject the ink to form dots corresponding to the image data on the printing medium. When suppression dots, which are dots formed to suppress bleeding, are formed on the printing medium, the dot forming unit controls the print head so that ink corresponding to the suppression dots is ejected from preceding nozzles arranged to eject ink to the printing medium earlier than other nozzles of the plurality of nozzles.

摘要： The attenuation characteristic of the surface potential of a photosensitive drum 20 is periodically detected. A target value −Vgt for a grid bias voltage −Vg applied to a charging unit 24, which is necessary to maintain, at a set value −Vods, the charging potential −Vod of the developing portion of the photosensitive drum 20, is derived from the detected attenuation characteristic. During image forming in which a developing unit 24 operates, the grid bias voltage −Vg of the charging unit 24 is set to the derived target value −Vgt.

摘要： A method for reducing edge effect (white gapping) between objects formed on a photoconductive member of an imaging device includes, during processing of a given color plane, partially exposing the photoconductive member for all image data that specifies a color to be developed on at least one color plane but that specifies no color to be developed on the given color plane. As such, the partial exposing does not enable development of that image data during image processing of the given color plane. By partially exposing objects that do not include a color to be developed on the color plane currently being processed, and while normally exposing adjacent objects that include a color to be developed on the current color plane, the lateral electric field effects between the objects is reduced and, thus, toner development for the given color plane is more edge precise for reduced white gapping between the objects.

摘要： An image forming apparatus includes an image carrier, a laser diode for generating a plurality of light beams, and a rotating polygonal mirror for simultaneously scanning the image carrier in a primary scanning direction along respective lines which are parallel to each other in a secondary scanning direction. The image carrier is scanned once for each of a plurality of different colors to thereby form a color image on the image carrier. A photosensitive sensor is provided for detecting an amount of deviation of the plurality of light beams in the primary scanning direction with respect to a first color of the plurality of different colors, and deviations among the plurality of light beams in connection with scanning for each of the plurality of different colors are corrected according to the detected amount of deviation with respect to the first color of the plurality of different colors.
