    Abstract: A distance between a reference position and a reference image of a sheet is accurately measured without adding a special device even when an attitude of the sheet is not stable. An aspect of the present invention obtains image data by reading a sheet surface formed with the reference image such as a trim mark by a reading portion. A height calculation portion calculates edge-blur amounts of the reference position and the reference image on the sheet surface from the image data. Furthermore, a height calculation portion detects heights from a focus position to the sheet surface for the reference position and the reference image, from the edge-blur amount and a reflected light amount of a white solid portion. Moreover, a distance detection portion calculates a distance between the reference position and the reference image on the sheet surface, on the basis of a detection result.

    Abstract: An image forming apparatus includes: an image forming mechanism that forms a first image on a recording medium based on an image forming condition; a detector that detects a first color of the first image and a color of a foundation under the first image from the recording medium on which the first image is formed; a storage that stores reference data for specifying a relative relationship between a position of the first color in a color space and a position of the color of the foundation in the color space; and a processing circuitry, wherein the processing circuitry corrects the image forming condition based on the reference data and the first color and the color of the foundation detected by the detector.

    Abstract: There is provided an image forming apparatus capable of suppressing fluctuation of sensor output. The image forming apparatus includes a photosensor and a hardware processor. The photosensor has a layered structure in which a surface layer is laminated on a base material layer, irradiates a surface of an image bearing member on which a toner image is formed with detection light on the basis of a predetermined detection condition, and receives reflected light of the detection light reflected from the surface of the image bearing member. The hardware processor controls at least a dominant wavelength of the photosensor among the predetermined detection conditions such that light interference and dark interference are included in the reflected light, and controls a toner adhesion amount onto the image bearing member on the basis of an output of the photosensor.

    Abstract: In an image-forming apparatus such as a printer, the controller judges whether or not a determination processing of fixity saturation state is performed to determine the fixing condition in which the image density of the patch is the fixity saturation state. The controller then performs the determination processing of fixity saturation state when the use condition is changed. The controller settles fixing conditions in which the image density of patch is highest as the set value when the image density of the patch is saturated. Next, the controller performs a toner adhesion amount adjustment using an intermediate transfer belt. A target value of the toner adhesion amount on the intermediate transfer belt corresponding to the target image density is set and then, an optimal developing voltage that is the set target value is set. After the toner adhesion amount adjustment, the controller performs fixity adjustment.

    Abstract: An image forming apparatus includes: an image former that forms a correction patch using toner; a measurer that measures a color, a density, or a deposited amount of toner of the correction patch; and a hardware processor that calculates a reference correction amount on the basis of a measurement value of the measurer so that the density of the correction patch reaches a target value, and corrects an image forming condition of the image former by a first correction amount smaller than the reference correction amount.

    Abstract: An image forming apparatus that forms an output image corresponding to input image data on an image carrier by superimposing toner images of colors, includes a hardware processor that: detects color information of the output image for every pixel region; converts color information of the input image data for every pixel region and color information of the output image for every pixel region into indexes which define colors in predetermined color space coordinates; extracts a pixel region in which the color information of the output image is different from the color information of the input image data, and corrects the color information of the input image data with respect to the extracted pixel region; and stores the color information of the input image data as data for calibration in combination with the color information of the output image and image :forming conditions when forming the output image.
