An image forming apparatus has a normal image formation mode and a wide color gamut image formation mode in which an amount of a developer per unit area of a developer image of at least a color that differs from a prescribed color among a plurality of colors is increased as compared to the normal image formation mode. Image data is generated such that an image portion formed in the prescribed color in an image formed on a recording material is formed solely by a developer image of the prescribed color in the normal image formation mode, but formed by superimposing a developer image of a color that differs from the prescribed color on a developer image of the prescribed color or formed solely by a developer image of a different color in place of a developer image of the prescribed color in the wide color gamut image formation mode.

Image forming apparatus

An image forming apparatus includes a first image forming unit, a second image forming unit, and a control unit configured to control the first image forming unit and the second image forming unit. The control unit performs control so as to allow execution of a first mode and a second mode in which a color gamut of an image to be formed on a printing material is expanded from the first mode, as an image forming mode for forming an image on a printing material. The second mode includes a second single-color mode in which image formation is performed by only the first image forming unit and a second multicolor mode in which image formation is performed by the first image forming unit and the second image forming unit.

An image forming apparatus includes an image forming unit configured to form an image on an intermediate transfer member; a transfer member configured to output a transfer voltage in order to cause a transfer current to flow so as to transfer the image to a sheet; a measurement unit configured to measure a density of the image; and a control unit configured to control the image forming unit to form a test image on the intermediate transfer member based on test image data, control the measurement unit to acquire a measured density of the test image, correct the measured density based on an evaluation value of an electric resistance of a path through which the transfer current flows, and generate data for density correction based on the test image data and a corrected measured density.

Image forming apparatus configured to generate data for density correction

An image forming apparatus, configured to operate in first and second modes of which color gamut is different from each other, includes an exposure unit configured to expose a photosensitive drum; a developing roller configured to form a toner image; a detection unit configured to detect density of the toner image transferred to an intermediate transfer member; and a controller configured to adjust the density based on a value of input image data. A dithering process for the controller's controlling of the exposure unit is different depending on whether the operation is in the first mode or the second mode, and in at least a part of the input image data, the density of the toner image formed by the dithering process in the first mode is higher than the density of the toner image formed by the dithering process in the second mode.
