  • Patent number: 9840092
    Abstract: Disclosed is an image forming apparatus including an image forming unit that ejects droplets from an image forming apparatus, and forms an image on a surface of a printing medium, a pre-processing unit that applies a pre-processing liquid to the surface of the printing medium before the image is formed by the image forming unit, and a post-processing unit that applies a post-processing liquid different from the pre-processing liquid to the surface of the printing medium after the image is formed by the image forming unit. The pre-processing unit applies an amount of the pre-processing liquid which is determined based on a type of the printing medium and the post-processing unit applies an amount of the post-processing liquid which is determined based on the type of the printing medium.

  • Patent number: 9254683
    Abstract: An image forming apparatus discharges ink onto a recording medium to form an image on a surface of the recording medium. The image forming apparatus includes a preprocessing unit that applies preprocess liquid on the surface of the recording medium before the image is formed; and a postprocessing unit that applies postprocess liquid, which is different from the preprocess liquid, onto the recording medium after the image is formed. An application quantity of the preprocess liquid is determined based at least on a kind of the ink, and an application quantity of the postprocess liquid is determined based at least on the kind of the ink.
