  • Publication number: 20230109578
    Abstract: A toner includes toner base particles each containing a binder resin and a release agent, and resin particles on a surface of each of the toner base particles. A ratio (Iw/Ir) is 0.10 or more and 0.30 or less, where Ir is a peak height of the binder resin and Iw is a peak height of the release agent, as measured through attenuated total reflection (ATR). A standard deviation ? (nm) of distances L (nm) between the resin particles that are adjacent to each other on the surface of each of the toner base particles is 150 nm or more and 500 nm or less.

  • Publication number: 20220342330
    Abstract: A toner includes toner base particles. Each of the toner base particles includes a binder resin, a colorant, and inorganic filler. An atomic concentration % of Al in the toner base particles as measured by XRF is 0.35 or greater but 0.85 or less. The toner satisfies 0.8<(M1/M2)/(M3/M4)<1.2. M1 is an atomic concentration % of Al in the toner base particles as measured by XPS, M2 is the atomic concentration % of Al in the toner base particles as measured by XRF, and M3 is an atomic concentration % of Al in particles as measured by XPS, and M4 is an atomic concentration % of Al in the particles as measured by XRF. The particles are particles obtained by classifying the toner base particles into 6/5 Dv, and Dv is a volume average particle diameter of the toner base particles.

  • Patent number: 9538058
    Abstract: The imaging device has a display section, an imaging section configured to generate an image of an object, an operation section configured to accept an operation, and a record control section. The record control section starts recording of video image data based on the generated image after a predetermined operation through the operation section is accepted and a predetermined period of time passes thereafter. Until the operation section accepts the predetermined operation, the display section displays a first mark in a first form. Until the predetermined period of time passes after acceptance of user operation thorough the operation section, the display section displays the first mark in a second form. After the predetermined period of time passes, the display section displays a second mark different from the first mark.

  • Patent number: 9263001
    Abstract: A display control device of the present disclosure is a device for controlling a video image displayed on a display unit. The display control device includes a controller configured to generate an image including a first image and a second image superimposed on the first image to display the image on the display unit. The controller performs control to display the first image of a first field angle on the display unit when a first mode is set, and performs control to display the first image of a second field angle which is wider than the first field angle on the display unit when a second mode is set. The second mode is a mode for setting a region of the second image in a region of the first image of the second field angle.

  • Publication number: 20130169761
    Abstract: An imaging apparatus can be connected to a 3D adapter having an optical system capable of condensing light for forming an image for a left-eye and light for forming an image for a right-eye and can be set into an adjusting mode for adjusting the optical system. The imaging apparatus includes an image pickup unit operable to capture an image formed based on the lights condensed by the 3D adapter, and a display unit operable to display the image captured by the image pickup unit. When the imaging apparatus is set to the adjusting mode, the display unit overlaps and displays the image for a left-eye and the right-eye image captured by the image pickup unit.
