<P>PROBLEM TO BE SOLVED: To highly precisely control toner density with a simple structure, in an image forming device. <P>SOLUTION: The image forming device is provided with a process control means 1 for deciding a process condition to obtain a desired solid density by selecting a process condition corresponding to environmental condition from a table prepared in advance, a pattern forming means 2 for forming a density pattern including a half-tone density level, a pattern detecting means 3 for detecting a formed density pattern, and an image data correcting means 4 for correcting image data based on the detected result by the pattern detection means 3. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
