摘要： Image forming apparatus (100) creates a toner pattern on intermediate transfer belt (11) as a preprocessing of gradation correction, and calculates a cycle at which density unevenness is largest. Then, a toner image for gradation correction is formed so as to cancel cyclic unevenness at a cycle at which the largest density unevenness occurs. As a result of this, it becomes possible to suppress the deterioration of density detection accuracy and perform a highly accurate gradation correction even if density unevenness of any cycle occurs.

摘要： Provided are an image forming apparatus and an image forming method capable of easily forming an output image having desired gradation characteristics and capable of reducing running cost. In an intermediate transfer-type image forming apparatus, an image forming section is configured by including a first image forming section which forms a color toner image on a photoconductor, and a second image forming section which is located on the upstream side of the first image forming section and forms a transparent toner image on the photoconductor. Further, after the transparent toner image is formed on an intermediate transfer member by the second image forming section, the first image forming section forms, on the basis of image data (correction gradation values) corrected by a gradation correcting section, a color toner image so that the color toner image is superimposed on the transparent toner image.

摘要： An image forming apparatus includes an image forming unit, a storage unit, an image processing unit and a control unit. The image processing unit (i) calculates a summed height of a color toner image formed on a sheet by summing up a height of the color toner image on the basis of input image data, (ii) calculates, on the basis of a target value for glossiness stored in the storage unit, a target total height of the color toner image and a clear toner image to realize the target value for glossiness, and (iii) calculates a height of the clear toner image by subtracting the summed height from the target total height. On the basis of the calculated height of the clear toner image, the control unit adjusts the height of the clear toner image formed on the sheet.
