摘要： A density detection apparatus includes the following elements. A storage unit stores therein image information. A measuring unit measures amounts of light components reflected by an image carrier or density detection images represented by the image information. A light amount obtaining unit obtains a variation in amounts of light components reflected by each region in which the associated density detection image is formed, and obtains, as a reference value, a representative value of the amounts of light components. An image correcting unit corrects the image information by changing an arrangement order of the density detection images. An image forming unit forms the density detection images on the image carrier on the basis of the corrected image information. A density obtaining unit obtains density levels of density detection images corresponding to their area ratios by using the amounts of light components reflected by the density detection images and the reference values.

摘要： An image forming apparatus includes a controller that provides control in which, if image formation processing by a single unit is executed first since a density adjustment condition for adjusting a density of an image is satisfied, a density adjustment value is changed by a predetermined basic change amount, and a first image is formed in a corresponding image formed region with a density that is adjusted in accordance with the changed density adjustment value, and control in which, if a single image other than the first image is formed in the corresponding image formed region, the current density adjustment value is changed by a predetermined fine change amount that is smaller than the basic change amount, and the single image is formed in the corresponding image formed region with a density that is adjusted in accordance with the changed density adjustment value.

摘要： A density detection apparatus includes the following elements. An image forming unit forms density detection images having different area ratios. A measuring unit measures an amount of reflected light. A storage unit stores reference values and also stores a representative value thereof. A determining unit determines a threshold for the area ratios of the density detection images on the basis of a variation among the reference values. A density obtaining unit obtains, for a density detection image having an area ratio which exceeds the threshold, a density level by using the amount of light reflected by the density detection image and the representative value, and obtains, for a density detection image having an area ratio which is equal to or smaller than the threshold, a density level by using the amount of light reflected by the density detection image, the associated reference value, and the representative value.
