Abstract: A recording apparatus includes an ink tank, a carriage, a recording head mounted on the carriage, a carriage control unit, and a supply tube connected to the recording head and the ink tank and including a bent portion that moves with carriage movement. The carriage control unit moves the carriage in predetermined directions to record on a recording medium. Assuming that, of an acceleration/deceleration area of a carriage moving area, an area in which pressure changes to decrease negative pressure in the recording head is a first area, and an area in which the pressure changes to increase the negative pressure in the recording head is a second area, the carriage control unit moves the carriage so that an absolute value of acceleration or deceleration of the carriage in the first area is less than an absolute value of acceleration or deceleration of the carriage in the second area.

Abstract: Reaction liquid application S1 to an ink receiving medium, formation of a first image by ink application S2, liquid absorption S3 from the first image by a porous body of a liquid absorbing member, cleaning S4 of the porous body, and liquid collection S5 from the porous body are repeated in an inkjet printing method. When the porous body comes into contact with the first image, first chemical species in the reaction liquid contributing to increasing the ink viscosity is contained, on the ink receiving medium and in the porous body, at a higher level in terms of molar equivalent per unit area than second chemical species in the ink also contributing to increasing the ink viscosity. In the liquid collection S5, the liquid is collected so that the liquid remains in the porous body on the side to be brought into contact with the first image.

Abstract: In a process of an ink receiving medium entering a nip part with a liquid absorbing member, force in a direction to sweep up an image to be processed as an absorption removal treatment target is reduced by changing a nip pressure of the nip part in a conveying direction of the ink receiving medium. Furthermore, when peeling off the liquid absorbing member from the ink receiving medium from the nip part, force for pulling a liquid component toward a porous body is effectively applied. As a result, it is possible to achieve high absorption and removal of the liquid component from the image to be processed while suppressing disturbance of the image to be processed.
