FIG. 3A shows a state in which the suction operation by the suction pump 8 is performed in this way, and after the suction operation, as shown by hatching in this figure, the lumen portion 5A and the tubes 7, 9 are shown. The ink 12 that has been ejected over a period of time is full. In this state, the surface of the absorber 11 and the ink ejection surface 1A
There is a slight gap between the cap member 5 and the arrow C, and the ink 12 is filled in this gap.
When the ink ejection surface 1A is moved backward and the contact surface 5B is separated from the ink ejection surface 1A, the water absorption effect of the absorber 11 causes the ink ejection surface 1A.
The upper ink is transferred to the absorber 11 together with the ink held in the gap to prevent the ink from remaining on the ink ejection surface 1A.

The reason why such adhered ink 13 remains will be described with reference to FIGS. 4A and 4B, and will be described with reference to FIGS. 4A and 4B corresponding to FIG. 3A and 4A corresponding to FIG. 3A.
At the moment when the cap member 5 tries to retract from the state shown in FIG. 4B, a slight gap 14 is generated between the ink ejection surface 1A and the cap member contact surface 5B. Before this state, the ink in the inner cavity portion 5A has a water absorbing effect of the absorber 11 and a water repellent treatment around the ink discharge port 1B. Absorber 11
However, the ink 13A remains in the contact portion 5B that keeps contact with the ink ejection surface 1A and in the vicinity thereof due to the capillary action of the gap 14 causing the ink to move in the direction of arrow E.

Therefore, when the cap member 5 is further retracted in the direction of arrow C from the state of FIG. 4B, the remaining ink 13A is separated into the ink ejection surface 1A side and the contact surface 5B of the cap member 5 as described above. As shown in FIG. 3B, the residual ink 13 remains attached and remains in the state shown in FIGS. 5A and 5B. As described above, in the conventional example, the ink ejection surface is recovered after the suction recovery.
Since the ink remains on the contact surface 5B of the cap member 5 and 1A, if the residual ink 13 on the ink ejection surface 1A side is left as it is, the residual ink 13 on a recording sheet (not shown) is recorded during the recording operation.
Contact and stain it with ink, or this residual ink 13
When a wiping operation is performed to clean the surface with a rubber blade or the like, since the amount of residual ink 13 on the ejection surface 1A is large,
Ink scatters on the recording sheet side and deteriorates the image quality.
Furthermore, if the residual ink 13 on the side of the cap member 5 is left as it is, the ink will be dried and fixed, resulting in poor adhesion between the ink ejection surface 1A and the cap member contact surface 5B, and a suction failure due to leakage. Generate. Further, even if the residual ink 13 on the ink ejection surface 1A side is removed by wiping, if the residual ink 13 on the cap member 5 side is left as it is, this residual ink 13 is transferred to the ink ejection surface 1A side during capping. There is a drawback that the ink ejection surface 1A that has been moved and cleaned by the corner wiping is stained again with the ink.

FIG. 1 shows an embodiment of the present invention, in which the state immediately after the recovery device 4 is mounted on the ink ejection surface 1A of the inkjet recording head 1 and the recovery operation is performed is shown. In FIG. 1, what is indicated by a continuous cross mark indicates a surface according to the present invention which is made to have water repellency. That is, the abutment surface 5B of the cap member 5, the surrounding cavity wall surface 5C which is continuous with the abutment surface 5B and forms the cavity portion 5A, and the above-mentioned contact surface of the ink ejection surface 1A of the recording head 1. The water repellent agent X is applied to the inside from the portion where the contact surface 5B abuts, thereby imparting the water repellent property.

Now, the behavior of the ink 12 during the recovery operation of the recording head 1 and the recovery device 4 that have been subjected to the water repellent treatment in this manner will be described with reference to FIGS. 2A and 2B. Immediately after the suction recovery operation, the inner cavity 5A of the cap member 5 is filled with the ink 12, but the ink ejection surface 1A of the recording head 1
2A on the contact surface 5B of the cap member 5 and the inner wall surface 5C.
As shown in the figure, since the water repellent agent X is applied, the spaces 20 where the ink 12 does not wrap around are formed at the four corners of the inner cavity portion 5B due to the relationship between the water repellent effect and the surface tension of the ink.

Therefore, after the recovery operation by suction, the cap member 5 is moved to the first position.
When the ink is retreated in the direction of arrow C as shown in FIG. 2B, the ink that has been in contact with the ink ejection surface 1A is adsorbed by the ink absorber 11, and the contact surface 5B and the inner wall surface 5C continuous with the contact surface 5B. Due to the water repellent property of the ink, it is possible to prevent the ink from remaining on these portions.

In addition, in the above-described embodiment, the configuration in which the water repellent agent is applied to both the ink ejection surface and the contact surface side of the cap member has been described, but the case where the water repellent agent is applied to either one of them is also applicable. When applied to the ink ejection surface side, ink can be prevented from remaining on the ink ejection surface, and when applied to the cap member side, ink remains on the contact surface of the cap member. It goes without saying that you can prevent this.

Further, in the above description, the configuration in which the repellent agent is applied to the recording head and the cap member side has been described. However, the contact portion of the recording head ink ejection surface that comes into contact with the cap member and the cap member itself are made of a highly water-repellent material. Even if it is formed by the same method, the same effect can be obtained. Therefore, for example, taking the side of the cap member as an example, silicone rubber can be cited as a material having a high water repellent property. Also, with ordinary silicon, the effect as shown in this example is difficult, so Teflon with high water repellent property,
Fluorine-based such as PTFE or silicon-based water repellent differentially adducted into the base rubber material for molding, or oil or wax is also adducted in the same manner to form Later, the water repellent property may be enhanced by utilizing the effect that the inversion product having high water repellent property as described above appears on the surface.
