  • Patent number: 10730330
    Abstract: An ink jet recording method is disclosed where, when a liquid including water is absorbed and removed from an image including an aqueous liquid component and a coloring material, by use of a water repellent porous body, a contact surface of the porous body with the image is treated with a wetting liquid whose contact angle to the contact surface is less than 90°, and thereafter absorption and removal of the aqueous liquid component from the image by the porous body are performed.
    Type: Grant

  • Patent number: 10556448
    Abstract: When a porous body is repeatedly used to perform treatment of absorbing and removing an aqueous liquid component on an image which is formed using a reaction liquid and an ink and contains the aqueous liquid component and a coloring material, recovery treatment for applying a recovery liquid to the porous body is performed, the recovery liquid having a viscosity lower than a viscosity of the reaction liquid and the ink.

  • Patent number: 10525700
    Abstract: A transfer type ink jet recording method including an image forming step of forming an image including an aqueous liquid component and a coloring material on an image forming surface of a transfer body, the image forming surface being formed of a water-repellent porous body; a transfer step of transferring the image from the transfer body onto a recording medium; a wetting treatment step of performing a wetting treatment by applying a wetting liquid whose contact angle with respect to the image forming surface is less than 90° onto the image forming surface before the image forming step; and a liquid absorbing step of absorbing at least part of the aqueous liquid component from the image formed in the image forming step by using the porous body in at least one of a period between the image forming step and the transfer step and a period in the transfer step.

  • Patent number: 10384470
    Abstract: An ink jet recording apparatus includes an image forming unit that forms a first image containing a first liquid and a coloring material on an ink receiving medium, a liquid absorbing member that has a porous body coming in contact with the first image and absorbing at least a part of the first liquid from the first image, and a liquid collecting device that collects the first liquid absorbed in the porous body. The porous body has a first surface that is a side contacting the first image, and a second surface opposing the first surface. An average pore size of the second surface of the porous body is larger than an average pore size of the first surface. In addition, the liquid collecting device includes a gas ejection member that ejects gas to the second surface of the porous body to extrude the first liquid from the second surface.
