Patent ID: 7583408

Claim:
An image-forming apparatus that forms an image by transferring a toner image formed on an image carrier onto a recording medium, the image-forming apparatus comprising: a density detector that detects a density of a toner image on the image carrier; a density adjuster that forms a correction pattern and performs an image-density adjustment on the basis of the correction pattern and the density of the toner image that is detected the density detector; an image-density calculator that calculates an image density in a predetermined section of an image represented by an image signal which is different from the correction pattern, the image density being calculated on the basis of the image signal; a comparator that compares the image density calculated by the image-density calculator and the result of detection performed by the density detector to obtain a density in the predetermined section of a toner image formed on the basis of the image signal; and a determiner that determines whether or not to cause the density adjuster to perform the image-density adjustment on the basis of the result of comparison performed by the comparator, wherein the predetermined section is a section in which the density based on the image signal is equal to or more than a predetermined value and a density dispersion based on the image signal is equal to or less than a predetermined value.
