## Abstract

An inkjet recording method including recording an image by applying an ink containing a pigment to a recording medium, and fixing an image region by pressure-contacting a pressure-bonding unit against the image region when the tackiness of the image region as measured by a ball tack test method reaches 20 mm or greater.

## Claims

### Claim 1

An inkjet recording method comprising:
recording an image by applying an ink including a pigment to a recording medium; and
fixing an image region by pressure-contacting a pressure-bonding unit against the image region when the tackiness of the image region as measured by a ball tack test method reaches 20 mm or greater.

### Claim 2 (depends on 1)

The inkjet recording method according to claim 1, wherein the tackiness of the image region measured by the ball tack test method reaches 20 mm or greater within 7 seconds from completion of the recording.

### Claim 3 (depends on 1)

The inkjet recording method according to claim 1, wherein the ink further includes a resin particle.

### Claim 4 (depends on 1)

The inkjet recording method according to claim 1, further comprising regulating the temperature of the image region to be 40° C. or higher before the fixing of the image region.

### Claim 5 (depends on 1)

The inkjet recording method according claim 1, wherein the concentration of solid content of the ink including the pigment is 8% by mass or more.

### Claim 6 (depends on 1)

The inkjet recording method according to claim 1, wherein the recording medium is selected from papers having a coating layer.

### Claim 7 (depends on 1)

The inkjet recording method according to claim 1, further comprising applying a treatment liquid including an aggregating agent which aggregates a component of the ink, to the recording medium.

### Claim 8 (depends on 7)

The inkjet recording method according to claim 7, wherein after the applying of the treatment liquid to the recording medium, the recording of the image by applying the ink is performed, and then the fixing of the recorded image region is performed.

### Claim 9 (depends on 1)

The inkjet recording method according to claim 1, wherein the fixing of the image region is performed by heating together with the pressure-contacting.

### Claim 10 (depends on 1)

The inkjet recording method according to claim 1, wherein the content of the pigment in the ink is from 1 to 25% by mass relative to the total amount of the ink.

### Claim 11 (depends on 1)

The inkjet recording method according to claim 1, wherein the pigment in the ink is an encapsulated pigment.

### Claim 12 (depends on 1)

The inkjet recording method according to claim 1, wherein the ink includes at least one water-soluble organic solvent.

### Claim 13 (depends on 3)

The inkjet recording method according to claim 3, wherein the resin particle in the ink includes a self-dispersing polymer.

### Claim 14 (depends on 13)

The inkjet recording method according to claim 13, wherein the content of water-soluble component of the self-dispersing polymer that exhibits water-solubility when the self-dispersing polymer is in a dispersed state, is 10% by mass or less relative to the total amount of the self-dispersing polymer.

### Claim 15 (depends on 1)

The inkjet recording method according to claim 1, wherein the ink includes water, and the content of the water is from 10% by mass to 99% by mass relative to the total amount of the ink.
