Image forming apparatus and image density adjustment method |
摘要 |
An image forming apparatus including: an image forming section which forms a belt-shaped pattern having a specific gradation and a prescribed length extending in a main-scanning direction; and a control section which receives pieces of density information each of which indicates a density of the belt-shaped pattern at a measurement position of measurement positions; detects a minimum density from the pieces of density information; sets the minimum density as a target density; identifies a first error between the target density and each of densities respectively indicated by the pieces of density information; sets a gradation correction amount at each of the measurement positions, respectively corresponding to the pieces of density information, based on the respective first errors; and corrects a gradation of image data based on the gradation correction amounts, wherein the image forming section forms an image based on the image data of which the gradation is corrected. |
