Abstract

The invention provides an intermediate transfer member for use in an image recording method including the steps of applying a reaction liquid to the intermediate transfer member, applying an ink to the intermediate transfer member so as to overlap with at least a part of a region to which the reaction liquid has been applied, thereby forming an intermediate image, and transferring the intermediate image to a recording medium, wherein an average of a surface area per unit area of a surface of the intermediate transfer member is 1.2 or more and 10.0 or less.

First claim

What is claimed is:

1. An intermediate transfer member for use in an image recording method comprising the steps of applying a reaction liquid to the intermediate transfer member, applying an ink to the intermediate transfer member so as to overlap with at least a part of a region to which the reaction liquid has been applied, thereby forming an intermediate image, and transferring the intermediate image to a recording medium,
wherein the intermediate transfer member has a surface such that 1.2≦S2/S1≦10, where S1 is a projection surface area in a direction perpendicular to the surface of the intermediate transfer member, S2 is an actual surface area of the intermediate transfer member, and S2/S1 is an average of a surface area per unit area of the surface of the intermediate transfer member, and
wherein the surface of the intermediate transfer member has a plurality of protruded structures having an average height of 0.05 μm to 1.00 μm.

2. The intermediate transfer member according to claim 1 , wherein when an average diameter of an ink droplet applied to the intermediate transfer member in the step of forming the intermediate image is regarded as R μm, a proportion of an area of portions where the protruded structures are present in a region of R μm×R μm in an ink-applicable portion on the surface of the intermediate transfer member is 90% or more.

3. The intermediate transfer member according to claim 1 , wherein the surface of the intermediate transfer member contains at least one selected from a fluorine compound and a silicone compound.

4. An image recording method comprising the steps of applying a reaction liquid to an intermediate transfer member, applying an ink to the intermediate transfer member so as to overlap with at least a part of a region to which the reaction liquid has been applied, thereby forming an intermediate image, and transferring the intermediate image to a recording medium, wherein the intermediate transfer member is the intermediate transfer member according to claim 1 .

5. The intermediate transfer member according to claim 1 , wherein the surface of the intermediate transfer member is such that 1.4≦S2/S1≦2.5.
