Abstract:
1. An image forming device for forming an image on an image carrier using a different grayscale reproduction method for each of two or more different attributes contained in portions of the image, the image forming device comprising: a standard pattern forming unit operable to form a different standard pattern on an image carrier in one-to-one correspondence with each different attribute contained in the image portions, wherein the different patterns are each formed using a different grayscale reproduction method used for reproducing image portions containing the attribute; a detecting unit comprising a sensor operable to detect density of each standard pattern formed by the standard pattern forming unit; a correction condition setting unit operable to set, for each different attribute, a condition for correcting grayscale of the image portions containing the attribute, in accordance with the density detected by the detecting unit; and a grayscale correcting unit comprising a processor operable to correct grayscale of the image portions on the image carrier in accordance with each condition set by the correction condition setting unit.
