Abstract
An inkjet recording device including an image support member in which a temperature-sensitive polymer layer is formed on the surface thereof; an ink discharge head which discharges, on the image support member, an ink obtained by dispersing a pigment into a water-based medium so as to form an image; a transfer roller which makes contact with the image support member; a second heating roller which heats the temperature-sensitive polymer layer; a water absorption roller that absorbs and removes water on the surface of the temperature-sensitive polymer layer. Thus, the bleeding of ink on a recording medium is reduced, and the efficiency of transfer of an image from the image support member to the recording medium is enhanced.
Claims6
An inkjet recording device comprising:
- a rotatable image support member in which a temperature-sensitive polymer layer that is reversibly changed from hydrophilic to hydrophobic by heating is formed on a surface of the image support member;
- an ink discharge unit which discharges, on the image support member, an ink obtained by dispersing a pigment into a water-based medium so as to form an image;
- a transfer unit which makes contact with the image support member so as to transfer the image formed on the image support member to a recording medium;
- and
- a first heating unit which heats the temperature-sensitive polymer layer,
- wherein, when the image is formed with the ink discharge unit, the temperature-sensitive polymer layer is changed to be hydrophilic so as to absorb water within the ink whereas, when the image formed on the image support member is transferred to the recording medium, the temperature-sensitive polymer layer is changed from hydrophilic to hydrophobic by heating with the first heating unit such that water is made to bleed from the temperature-sensitive polymer layer and that adherence of the pigment to the temperature-sensitive polymer layer is reduced.
