  • Publication number: 20190187606
    Abstract: There is disclosed an image post-processing method for adjusting glossiness of a fixed toner image. The method includes a glossiness control step and a temperature control step. The glossiness control step is a step of, to a toner image formed of a toner containing a light absorbing compound and fixed to a recording medium, emitting glossiness control light so as to reduce or increase glossiness of the toner image. The temperature control step is a step of heating the toner image immediately before the light is emitted to the toner image such that the toner image has a surface temperature which is at least 20° C. lower than a softening temperature of the toner. The glossiness control light has a maximum emission wavelength in a wavelength range in which the compound absorbs light and is made to at least reduce the glossiness of the toner image.

  • Patent number: 8198603
    Abstract: A sample preparing device has a sample stage that supports a sample and undergoes rotation about a first rotation axis to bring a preselected direction of the sample piece into coincidence with an intersection line between a first plane formed by a surface of the sample piece and a second plane. A manipulator holds sample piece of the sample and undergoes rotation about a second rotation axis independently of the sample stage to rotate the sample piece to a preselected position in the state in which the preselected direction of the sample piece coincides with the intersection line. The manipulator is disposed relative to the sample stage so that an angle between the second rotation axis and the surface of the sample is in the range of 0° to 45°.
