Ink jet recording apparatus
Disclosed is an ink jet recording apparatus that prints an image onto a recording medium using an ink which is composed of an aqueous ink vehicle containing latex as a binder resin. The ink jet recording apparatus includes a carriage on which a recording head for discharging ink droplets onto the recording medium is mounted and that moves relative to the recording medium, in which an infrared heater that is disposed opposite to the recording medium and heats the recording medium is mounted on the carriage, and the infrared heater is disposed to be distant from the recording head in a moving direction (X direction) of the recording medium.
1. An ink jet recording apparatus that prints an image onto a recording medium using an ink which is composed of an aqueous ink vehicle containing latex as a binder resin, the ink jet recording apparatus comprising:
a print heater that is a platen heater that heats the recording medium from a lower side of the recording medium,
a carriage on which a recording head for discharging ink droplets onto the recording medium is mounted and that moves relative to the recording medium,
wherein an infrared heater that is disposed opposite to the recording medium and heats the recording medium from an upper side of the recording medium is mounted on the carriage, and
the infrared heater is disposed to be distant from the recording head in a moving direction of the recording medium,
wherein the recording medium is heated from the lower side with the platen heater and from the upper side with the infrared heater, each heating temperature of the platen heater and the infrared heater is reduced than a heating temperature which the recording medium is heated only by the platen heater or only by the infrared heater.
2. The ink jet recording apparatus according to claim 1 , wherein
the infrared heater is disposed on only a downstream side of the recording head in the moving direction of the recording medium.
3. The ink jet recording apparatus according to claim 2 , further comprising:
a controller that controls a heating temperature of the recording medium,
wherein the controller controls the heating temperature of the recording medium such that a surface temperature of the recording medium immediately below the recording head for discharging ink droplets onto the recording medium is in a range of 60° C. to 80° C.
4. The ink jet recording apparatus according to claim 1 , wherein
warm-air heaters that heat the recording medium are further mounted on the carriage, and
the warm-air heaters are disposed at front and rear positions of the recording head in a reciprocating direction of the carriage to overlap with the recording head in the moving direction of the recording medium.
5. The ink jet recording apparatus according to claim 1 , further comprising:
a controller that controls a heating temperature of the recording medium,
wherein the controller controls the heating temperature of the recording medium such that a surface temperature of the recording medium immediately below the recording head for discharging ink droplets onto the recording medium is in a range of 60° C. to 80° C.
