Abstract

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

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.
