  • Patent number: 11480890
    Abstract: An image forming apparatus includes: a developing roller; a photosensitive drum; a first measurement device that measures a blank portion current in a first line on the photosensitive drum which extends in a scanning direction of the photosensitive drum and on which no toner patch is formed; a second measurement device that measures a measuring development current in a second line on the photosensitive drum which extends in the scanning direction of the photosensitive drum and on which a toner patch is formed; and a control device that functions as a patch setter and a first calculator. The patch setter sets a patch width of the toner patch in the scanning direction of the photosensitive drum. The first calculator calculates an actual development current based on a developable width of the photosensitive drum in the scanning direction, the patch width, the blank portion current, and the measuring development current.

  • Patent number: 11467523
    Abstract: An image forming apparatus includes a developing roller, a photoconductor drum, a density detector, a current detector, and a controller. The developing roller carries a toner. The photoconductor drum carries a toner patch. The density detector detects toner density of the toner patch. The current detector detects developing current flowing to the toner patch. The controller calculates an inclination of an approximate straight line approximating a relation between the toner density and the developing current. The developing roller develops three or more toner patches, different in toner density and different in developing current from one another, on the photoconductor drum. The controller calculates the inclination, using different mathematical expressions depending on whether three toner patches or four toner patches are provided.

  • Patent number: 11330144
    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: A display device includes a panel device and a hardware processor. The hardware processor controls the panel device in a first mode for displaying first image data, and controls the panel device in a second mode for displaying second image data in a case that an abnormality in display of the first image data is detected. In the second mode, the hardware processor: reads out the second image data from a memory of the display device; displays the second image data on the panel device in place of the first image data; determines presence or absence of a touch on the panel device based on a touch detection signal acquired from the panel device; and outputs, to the external system, an execution command to execute predetermined processing in response to determining that the touch on the panel device is present.

  • Patent number: 11134175
    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.
