An image processing apparatus accurately compensates a flare component. An image forming apparatus reads images in a first reading condition and a second reading condition in which flare less occurs, and includes: a reflectance assignment unit for assigning a reflectance to the first image in accordance with the distance between the first image and the second image; a color information arithmetic unit for obtaining color information about the first image read in the second reading condition; a flare component derivation unit for deriving a flare component of the second image based on the reflectance and the color information; and a flare component removing unit for removing a flare component of the second image read in the first reading condition, based on the second image read in the first reading condition and the flare component derived by the flare component derivation unit.

An image forming apparatus includes a conversion unit, an image bearing member, an image forming unit that forms an image on the image bearing member based on image data converted by the conversion unit, a measuring unit that measures a measurement image on the image bearing member, and a controller that controls the image forming unit to form a first measurement image, controls the measuring unit to measure the first measurement image, and generates a conversion condition based on a result of measurement of the first measurement image and a first feedback condition. In forming a chromatic color image after a predetermined number of monochrome images, the controller controls the image forming unit to form a second measurement image, controls the measuring unit to measure the second measurement image, and generates the conversion condition based on a result of measurement of the second measurement image and a second feedback condition.

An image forming apparatus includes a toner image forming section, a detection section, a variation calculation section, a user setting acquisition section, an adjustment ratio calculation section, and an adjustment section. The toner image forming section forms a toner image. The detection section detects a toner density of the formed toner image. The variation calculation section obtains a variation in toner density based on the detected toner density. The user setting acquisition section acquires a user setting concerning a degree of adjusting the toner density. The user setting is set by a user. The adjustment ratio calculation section calculates an adjustment ratio which is a ratio at which the user setting is reflected, in accordance with the variation in toner density. The adjustment section adjusts the toner density based on the variation in toner density, the user setting, and the adjustment ratio.

An image forming apparatus includes an exposure part forming an electrostatic latent image on a charge region, a developer carrier developing the electrostatic latent image into two types of development images (printing developer image and no-printing developer image), a supply member supplying developer to the developer carrier, a first detection part detecting a first physical quantity correlating to the density of the no-printing developer image, a setting part performing a setting, based on the first physical quantity, for a development voltage applied to the developer carrier or a supply voltage applied to the supply member, a second detection part detecting a second physical quantity correlating to a number of rotations after the print of the printing developer image starts, a correction part correcting, based on the second physical quantity, the development voltage or the supply voltage set by the setting part, and a power source part applying the development voltage to the developer carrier and applies the supply voltage to the supply member.

An image forming apparatus includes an image former, a detector, and circuitry. The image former forms a toner pattern with a first line screen; and forms a toner image based on image data, with a second line screen. The detector detects density unevenness of the toner pattern, formed by the image former, in a main scanning direction. The circuitry is configured to calculate a first correction amount from the density unevenness detected by the detector; create a gradation correction table that reduces the density unevenness based on the first correction amount; and correct the first correction amount by a second correction amount corresponding to the second line screen, in a case where the first line screen is different from the second line screen.

A system including a printer which performs printing on a recording medium according to a print job includes a display configured to display information, acquires first color tones, on a member halfway through print processing, of at least a first print job and a second print job, and acquires second color tones, on the recording medium subjected to printing, of at least the first print job and the second print job, wherein the display displays first color information that is based on the first color tones of at least the first print job and the second print job and second color information that is based on the second color tones of at least the first print job and the second print job.

An image forming apparatus includes an image forming unit configured to form an image, a conveyance unit configured to convey a sheet on which a test image has been formed, a sensor configured to read the test image on the sheet, while the sheet is being conveyed by the conveyance unit, and a controller. The controller causes the image forming unit to form a test image on each of a first sheet and a second sheet succeeding the first sheet, and based on a reading result of the test image on the first sheet read by the sensor and a reading result of the test image on the second sheet read by the sensor, suppresses density unevenness, in a conveyance direction in which the sheet is conveyed, of the image to be formed by the image forming unit.
