  • Patent number: 10012941
    Abstract: An image processing apparatus includes a printer device and an adjustment part. The printer device includes: an image formation unit that forms a toner image on a medium with toners including a regular toner and a special toner; and a fixation unit that performs a predetermined number of fixation operations of fusing the toner image on the medium. The adjustment part causes the printer device to print a first sample image using the special toner at various density levels, and receives a first setting for the density level of the special toner based on the printed first sample image. The printer device forms the toner image on the medium based on the first setting received, and fixes the toner image on the medium.

  • Patent number: 8983345
    Abstract: A developer supplying member is provided for supplying developer to a developer supporting member. The developer supplying member includes a foamed member having a discrete foam cell structure and being formed of a silicone rubber as a main component thereof. The foamed member constitutes a surface of the developer supplying member. The foamed member includes a foam cell wall dividing foam cells thereof and being exposed on the surface of the developer supplying member. The foam cell wall has a ten-point average surface roughness between 45.2 ?m and 65.3 ?m.
