## Abstract

There is provided an intermediate transfer body for transfer inkjet printing methods in which an image is formed by selectively applying image-forming ink using an inkjet device to the intermediate transfer body and then transferred from the intermediate transfer body to a recording medium to form a transferred image. The intermediate transfer body satisfies the relation E1<E2, where E1 is the compressive elastic modulus of the intermediate transfer body [Pa] measured in the direction parallel to that of the pressure generated during the compression process for image transfer, and E2 is the compressive elastic modulus of the intermediate transfer body [Pa] measured in the direction perpendicular to that of the pressure generated during the compression process for image transfer and parallel to that of conveyance of the recording medium. There is also provided a transfer inkjet printing apparatus having such an intermediate transfer body.

## Claims

### Claim 1

A transfer inkjet printing method comprising:
selectively applying an ink for forming some image using an inkjet device to an intermediate transfer body to form an image; and
pressing a recording medium onto the image so that the image should be transferred from the intermediate transfer body to the recording medium to form a transferred image,
wherein the intermediate transfer body has E1 and E2 satisfying a relation E1<E2, where E1 is a compressive elastic modulus of the intermediate transfer body measured in a direction parallel to a direction of a pressure generated while the recording medium is pressed onto the intermediate transfer body, and E2 is a compressive elastic modulus of the intermediate transfer body measured in a direction perpendicular to a direction of a pressure generated while the recording medium is pressed onto the intermediate transfer body and parallel to a direction of conveyance of the recording medium, and
wherein
E1×1.5<E2,
10(MPa)≦E1≦30(MPa); and
10(MPa)≦E2≦40(MPa).

### Claim 2 (depends on 1)

The transfer inkjet printing method according to claim 1,
wherein the intermediate transfer body comprises a fluorocarbon rubber exposed on a surface thereof.

### Claim 3 (depends on 1)

The transfer inkjet printing method according to claim 1,
wherein the intermediate transfer body comprises a silicone rubber exposed on a surface thereof.

### Claim 4 (depends on 1)

The transfer inkjet printing method according to claim 1,
wherein the intermediate transfer body comprises a needle-shaped filler.
