An image forming apparatus includes: a charging unit that uniformly charges a surface of a latent image carrier; a latent-image forming unit; a developing unit that performs development by causing toner to electrostatically adhere on the surface of the carrier; a transfer unit that transfers a toner image onto a recording medium; and an image-density adjusting unit that causes to form a multi-gradation patch pattern on the surface of the carrier, that causes to detect potentials of latent image patches in the multi-gradation patch pattern, that causes to detect a toner adhesion amount on each toner patch, and that performs control of an image density. One of part and all of the low-density latent image patches is a dot-dispersed latent image patch in which the arrangement of unit dot latent images in the basic dot matrix is determined so that a minimum center-to-center distance having a smallest value is maximized. |
