摘要： PROBLEM TO BE SOLVED: To realize an image forming apparatus capable of rapidly performing density correction processing, and performing an appropriate printing to all the jobs stored in an image memory. SOLUTION: When the density correction practicing condition of an image outputting part 74 is satisfied during printing of a certain job, a density correcting means 75 performs the density correction processing during outputting the printing job at that time or after outputting. In addition, when there exist jobs for waiting for printing stored in the image memory 72 at that time, the printing of these jobs is performed by an image forming condition (the amount of correction stored in a storing part 731 for the present amount of correction) before the density correction processing. To the jobs stored in the image memory 72 after the density correction processing, the printing is performed by a latest image forming condition (the amount of correction stored in a storing part 732 for the latest amount of correction) required by the density correction processing.

摘要： PROBLEM TO BE SOLVED: To provide an image adjusting method by which wasteful consumption of developer, etc., is suppressed when color matching adjustment is performed and the color matching adjustment can be efficiently performed in a short period of time and to provide an image forming apparatus. SOLUTION: A cyan correction patch image is printed in an image forming position corresponding to a correction value (i) (S32), and it is decided whether the correction patch image matches a reference patch image (S33). If it is decided that they do not match (S33:NO), the correction value is updated to continue the adjustment of cyan color matching. If it is decided that they match (S33:YES), printing of the cyan correction patch image is stopped, and a correction patch image of another color (e.g., magenta) is printed to adjust color matching (S35, S36).
