  • Publication number: 20250001766
    Abstract: An image forming apparatus includes an intermediate transfer body, a first coating device to coat the intermediate transfer body with a pre-coating liquid, a second coating device to coat the intermediated transfer body coated with the pre-coating liquid with an ink containing a solvent and a resin dissolved in the solvent, in which the resin includes a coloring material, and to mix the pre-coating liquid and the solvent to deposit the resin at a gas-liquid interface on the intermediate transfer body, and a heater to heat the resin deposited at the gas-liquid interface on the intermediate transfer body.

  • Patent number: 12162266
    Abstract: A drying apparatus includes a drying chamber to dry a drying-target medium with a gas maintained at a preset temperature, and the drying-target medium is a medium to be dried. The drying chamber takes in the gas from a suction chamber into which a gas is sucked in through an intake hole in a retaining face on which the drying-target medium is retained with the gas sucked into the suction chamber.
    Type: Grant

  • Patent number: 10894270
    Abstract: A liquid jet discharge device includes: a narrow tube having a tube shaped body that is open at both ends, and in which a discharge liquid being disposed therein, the discharge liquid contacting at least at an inner face of the narrow tube at a contact angle of less than 90 degrees; a container in which a transmission medium being disposed at a base side thereof where one end of the narrow tube is disposed, so as to enable pressure to be transmitted to the discharge liquid; an adjustment mechanism that causes a liquid surface of the discharge liquid inside the narrow tube and an interface of the transmission medium outside the narrow tube and inside the container to be staggered in position along an axial direction of the narrow tube; and a generation mechanism that generates a pressure wave in the transmission medium such that a liquid jet is discharged from the discharge liquid inside the narrow tube.
