Abstract
An image forming apparatus includes a first image forming unit for forming a color developer image using color developer; a second image forming unit for forming a transparent developer image using transparent developer; a transfer unit for transferring the transparent developer image and the color developer image to a medium; a fixing unit for fixing the transparent developer image and the color developer image; and a control unit for controlling the first image forming unit and the second image forming unit according to a gloss printing operation when the gloss printing operation is selected.
Claims21
An image forming apparatus comprising:
- a first image forming unit for forming a color developer image using color developer;
- a second image forming unit for forming a transparent developer image using transparent developer;
- a transfer unit for transferring the transparent developer image and the color developer image to a medium;
