Abstract
Official abstract text for this publication.
A transfer-type ink jet recording apparatus including an intermediate image forming unit for applying an ink containing a resin to an intermediate transfer member to form an intermediate image and a transfer unit for transferring the intermediate image to a recording medium. The apparatus further includes a heating unit for heating the intermediate image to a temperature equal to or higher than the minimum film forming temperature of the resin and a cooling unit for cooling the intermediate image heated by the heating unit to a temperature lower than the glass transition temperature of the resin to supply the image to the transfer unit.
First claim
Opening claim text (preview).
What is claimed is: 1. A transfer-type ink jet recording apparatus comprising an intermediate image forming unit for applying an ink containing a resin to an intermediate transfer member to form an intermediate image and a transfer unit for transferring the intermediate image to a recording medium, wherein the apparatus further comprises a heating unit for heating the intermediate image to a temperature equal to or higher than a minimum film forming temperature of the resin and a cooling unit for cooling the intermediate image heated by the heating unit to a temperature lower than a glass transition temperature of the resin to supply the image to the transfer unit. 2. The transfer-type ink jet recording apparatus according to claim 1 , wherein a surface of the recording medium to which the intermediate image is transferred is subjected to a hydrophilization treatment. 3. The transfer-type ink jet recording apparatus according to claim 1 , wherein a surface roughness Ra of an intermediate image forming surface of the intermediate transfer member is 0.1 μm or less. 4. The transfer-type ink jet recording apparatus according to claim 1 , wherein the apparatus has a transfer unit for transferring the intermediate image cooled by the cooling unit as a first transfer unit, a transfer unit for transferring the intermediate image heated by the heating unit to the recording medium at a temperature not lower than the glass transition temperature of the resin contained in the ink as a second transfer unit, and a switching unit for selectably conducting switching to one of intermediate image transfer modes of the first transfer unit and the second transfer unit. 5. The transfer-type ink jet recording apparatus according to claim 1 , further comprising a transfer aid liquid applying unit for applying a transfer aid liquid for improving transferability to the intermediate image. 6. The transfer-type ink jet recording apparatus according to claim 5 , wherein the transfer aid liquid contains a resin. 7. The transfer-type ink jet recording apparatus according to claim 1 , wherein the ink further contains a coloring material and a liquid medium. 8. The transfer-type ink jet recording apparatus according to claim 1 , wherein the ink is an aqueous ink. 9. The transfer-type ink jet recording apparatus according to claim 1 , wherein the apparatus has a reaction liquid applying unit for applying a reaction liquid for increasing the viscosity of the ink. 10. The transfer-type ink jet recording apparatus according to claim 1 , wherein the intermediate image cooled by the cooling unit is brought into contact with the recording medium in a softened state.
