Abstract
According to an embodiment, an image forming apparatus includes an image forming device, a scanning device, and a controller. The image forming device forms a first test image and forms a second test image. The scanning device scans the first test image with a first amount of emitted light corresponding to a first input value and scans the second test image with a second amount of emitted light corresponding to a second input value. The controller selectively executes any one of a first correction process, a second correction process, or a third correction process on the basis of an event change.
Claims10
An image forming apparatus that forms an image with a plurality of colors, comprising:
- an image forming device that forms a first test image on a basis of first test image data associated with a plurality of colors and forms a second test image on a basis of second test image data associated with a plurality of colors;
- a scanning device that scans the first test image with a first amount of emitted light corresponding to a first input value and scans the second test image with a second amount of emitted light corresponding to a second input value;
- and
- a controller that selectively executes any one of a first correction process, a second correction process, or a third correction process on a basis of an event change, wherein
- the first correction process includes a first light amount correction process of correcting the first input value so as to maintain the first amount of emitted light and an image density correction process of correcting density of the image to be formed on a basis of a result of scanning the first test image,
- the second correction process includes a second light amount correction process of correcting the second input value so as to maintain the second amount of emitted light and the image density correction process, and
- the third correction process includes a color distortion correction process of correcting color distortion of the image to be formed on a basis of a result of scanning the second test image.
A control method for an image forming apparatus that forms an image with a plurality of colors, comprising:
- forming, by an image forming device, a first test image on a basis of first test image data associated with a plurality of colors and forms a second test image on a basis of second test image data associated with a plurality of colors;
- scanning, by a scanning device, the first test image with a first amount of emitted light corresponding to a first input value and scans the second test image with a second amount of emitted light corresponding to a second input value;
- and
- selectively executing, by a controller, any one of a first correction process, a second correction process, or a third correction process on a basis of an event change, wherein
- the first correction process includes a first light amount correction process of correcting the first input value so as to maintain the first amount of emitted light and an image density correction process of correcting density of the image to be formed on a basis of a result of scanning the first test image,
- the second correction process includes a second light amount correction process of correcting the second input value so as to maintain the second amount of emitted light and the image density correction process, and
- the third correction process includes a color distortion correction process of correcting color distortion of the image to be formed on a basis of a result of scanning the second test image.
