On a conveyance path of a liquid absorbing member including a porous body, a liquid absorbing unitthat absorbs a first liquid from a first image, a recovery liquid applying unitthat applies a recovery liquid to the porous body absorbing the liquid and a liquid collecting unitthat collects a liquid component absorbed by the porous body are arranged in this order, and a cleaning unitthat brings a cleaning member into contact with the conveyance path of the porous body is disposed at least between the liquid absorbing unit and the recovery liquid applying unit or between the liquid collecting unit and the liquid absorbing unit.

Ink jet printing apparatus and ink jet printing method

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&#xb0;, and thereafter absorption and removal of the aqueous liquid component from the image by the porous body are performed.

Ink jet recording apparatus and ink jet recording method

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.

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&#xb0; 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.

Transfer type ink jet recording method and transfer type ink jet recording apparatus

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.

An ink jet recording apparatus includes a liquid collecting device including a compression member configured to compress a first porous body from a second surface opposite to a first surface that comes into contact with a first image, to extrude and collect a liquid component containing a first liquid from the first surface of the first porous body, and the liquid collecting device includes a second porous body configured to absorb the liquid component extruded from the first surface of the first porous body.
