| 发明名称 | Image forming apparatus for performing registration and density correction control | ||
| 摘要 | An image forming apparatus includes: an image forming unit configured to form, on an image carrier, a first correction pattern including developer images of a plurality of colors, and a second correction pattern including developer images of the plurality of colors; a registration correction unit configured to perform registration correction control based on a detection result of the developer images of the first correction pattern; and a density correction unit configured to perform density correction control based on a detection result of the second correction pattern. The density correction unit is further configured to decide a detection result of the developer image of at least one color of the second correction pattern used for the density correction control based on a detection result of the developer image of the first correction pattern. | ||

| 主权项 | 1. An image forming apparatus comprising: an image forming unit configured to form, on an image carrier, a first correction pattern including developer images of a plurality of colors, and a second correction pattern including developer images of the plurality of colors; a registration correction unit configured to perform registration correction control based on a detection result of the developer images of the plurality of colors of the first correction pattern; a density correction unit configured to perform density correction control based on a detection result of the developer images of the plurality of colors of the second correction pattern; and a calculating unit configured to calculate a misregistration amount between a first color and a second color of the plurality of colors based on the detection result of the developer images of the plurality of colors of the first correction pattern, wherein the density correction unit is further configured to determine a detection result of a developer image of the second color of the second correction pattern used for the density correction control based on the misregistration amount between the first color and the second color. | ||
