Abstract
An image forming apparatus includes: a first image forming portion configured to form a brilliant developer image with a brilliant developer; a second image forming portion including at least one image forming portion configured to form a developer image with at least one non-brilliant developer; and a controller configured to control operation of the first image forming portion and the second image forming portion in accordance with received print data. When the controller causes the brilliant developer image to be formed on a medium in accordance with the print data by the first image forming portion, the controller causes a black developer image to be formed between the brilliant developer image and the medium by the second image forming portion.

An image forming apparatus, comprising:
- a first image forming portion configured to form a brilliant developer image with a brilliant developer;
- a second image forming portion including at least one image forming portion configured to form a developer image with at least one non-brilliant developer;
- and
- a controller configured to control operation of the first image forming portion and the second image forming portion in accordance with received print data,
- wherein when the controller causes the brilliant developer image to be formed on a medium in accordance with the print data by the first image forming portion, the controller causes a black developer image to be formed between the brilliant developer image and the medium by the second image forming portion, and
- wherein when the controller causes the brilliant developer image to be formed on the medium in accordance with the print data, the controller performs control to cause the black developer image to be formed between the brilliant developer image and the medium such that an amount of developer per unit area of the black developer image is less than an amount of developer per unit area of the brilliant developer image.
An image forming apparatus, comprising:
- a first image forming portion configured to form a brilliant developer image with a brilliant developer;
- a second image forming portion including at least one image forming portion configured to form a developer image with at least one non-brilliant developer;
- and
- a controller configured to control operation of the first image forming portion and the second image forming portion in accordance with received print data,
- wherein when the controller causes the brilliant developer image to be formed on a medium in accordance with the print data by the first image forming portion, the controller causes a black developer image to be formed between the brilliant developer image and the medium by the second image forming portion, and
- wherein the controller performs control to cause the black developer image to be formed between the brilliant developer image and the medium such that a print image density of the black developer image is less than a print image density of the brilliant developer image.
An image forming apparatus, comprising:
- a first image forming portion configured to form a brilliant developer image with a brilliant developer;
- a second image forming portion including at least one image forming portion configured to form a developer image with at least one non-brilliant developer;
- and
- a controller configured to control operation of the first image forming portion and the second image forming portion in accordance with received print data,
- wherein when the controller causes the brilliant developer image to be formed on a medium in accordance with the print data by the first image forming portion, the controller causes a black developer image to be formed between the brilliant developer image and the medium by the second image forming portion, and
- wherein when the controller performs control to cause the black developer image to be formed between the brilliant developer image and the medium, the controller performs control so that a ratio R of an amount of developer per unit area of the black developer image to an amount of developer per unit area of the brilliant developer image satisfies
- 0.068≤R≤0.23.
