Recording apparatus
A recording apparatus including: an intermediate transfer member; an image forming composition layer formation unit that supplies an image forming composition to the intermediate transfer member, the image forming composition containing a curable material that cures upon application of an external stimulus; an ink application unit that applies ink to the image forming composition layer that has been formed on the intermediate transfer member; a transfer unit that transfers the image forming composition layer from the intermediate transfer member to a recording medium by contacting the image forming composition layer onto which the ink has been applied with the recording medium; and a first stimulus application unit that applies a stimulus to the image forming composition layer that cures the image forming composition layer, the stimulus being applied at least one of immediately before the image forming composition layer comes into contact with the recording medium, or during the contact.
1. A method of forming an image, comprising:
forming an image forming composition layer by supplying an image forming composition liquid to an intermediate transfer member, the image forming composition liquid containing a curable material that cures upon application of an external stimulus;
applying an ink to the image forming composition layer that has been formed on the intermediate transfer member, the ink being an ink in which a water-soluble dye or pigment is dispersed or dissolved in an aqueous medium, and which does not contain a curable material;
transferring the image forming composition layer from the intermediate transfer member to a recording medium by contacting the image forming composition layer onto which the ink has been applied with the recording medium;
applying a first stimulus to the image forming composition layer that cures the image forming composition layer, the first stimulus being applied at least one of immediately before the image forming composition layer comes into contact with the recording medium, or during the contact; and
applying a second stimulus that cures the image forming composition layer, the second stimulus being applied to the image forming composition layer after it has been released from the intermediate transfer member;
wherein the first stimulus and the second stimulus are each light including UV rays, and a ratio represented by I 1C /I 1T is larger than a ratio represented by I 2C /I 2T , and wherein:
I 1T is an integrated irradiation intensity of the light including UV rays in a wavelength range of from 250 nm to 500 nm, and I 1C is an integrated irradiation intensity of the light including UV rays in a wavelength range that cures the image forming composition layer; and
I 2T is an integrated irradiation intensity of the light including UV rays in a wavelength range of from 250 nm to 500 nm, and I 2C is an integrated irradiation intensity of the light including UV rays in a wavelength range that cures the image forming composition layer.
2. The method according to claim 1 , wherein a surface of the intermediate transfer member that contacts the image forming composition layer has a surface free energy is less than a surface free energy of a surface of the recording medium that contacts the image forming composition layer.
3. The method according to claim 2 , wherein the surface of the intermediate transfer member that contacts the image forming composition liquid contains a fluorine-based resin.
4. The method according to claim 1 , wherein the first stimulus is applied to the image forming composition layer through the intermediate transfer member.
5. The method according to claim 3 , wherein the first stimulus is applied from the inside of the intermediate transfer member.
6. The method according to claim 1 , wherein the curable material is selected from the group consisting of a UV-ray curable material, an electron-beam curable material, and a thermally curable material.
7. The method according to claim 1 , wherein the amount of the first stimulus is not less than the amount of the stimulus that cures the image forming composition layer to a curing ratio of about 10% but less than the amount of the stimulus that cures the image forming composition layer to a curing ratio of about 80%, and
the total amount of the first stimulus and the second stimulus is not less than the amount of the stimulus that cures the image forming composition layer to a curing ratio of about 80%.
8. The method according to claim 1 , wherein the first stimulus is supplied from an UV-emission diode.
