发明名称 IMAGE FORMING DEVICE, DENSITY CORRECTION METHOD, AND NON-TRANSISTORY COMPUTER READABLE STORAGE MEDIUM STORING PROGRAM
摘要 An image forming device includes a density correction unit that corrects density based on a density detection value of the density correction pattern; a first density correction pattern generating unit that generates a first density correction pattern having low resolution; and a second density correction pattern generating unit that generates a second density correction pattern having high resolution. When a first density detection value of the first density correction pattern is greater than a predetermined threshold value, the density correction unit corrects the density by determining a density correction reflection rate, based on the first density detection value. When the first density detection value is less than or equal to the predetermined threshold value, the density correction unit corrects the density by determining the density correction reflection rate, based on a second density detection value of the second density correction pattern.

主权项 1. An image forming device comprising: an image forming unit configured to form a density correction pattern on an image carrier; a detection unit configured to detect density of the density correction pattern formed on the image carrier; a density correction unit configured to correct the density based on a density detection value of the density correction pattern; a first density correction pattern generating unit configured to generate a first density correction pattern having resolution which is lower than that of a pattern used for actual image printing; a second density correction pattern generating unit configured to generate a second density correction pattern having high resolution, wherein the second density correction pattern is used for actual image printing; and a determination unit configured to compare a density detection value of the density correction pattern with a predetermined threshold value, wherein, when a first density detection value of the first density correction pattern is greater than the predetermined threshold value, the density correction unit corrects the density by determining a density correction reflection rate, based on the first density detection value of the first density correction pattern, and wherein, when the first density detection value is less than or equal to the predetermined threshold value, the density correction unit corrects the density by determining the density correction reflection rate, based on a second density detection value of the second density correction pattern.
