2. Description of the Related Art In recent years, a recording apparatus using a thermal recording head is easy to handle since it does not require development and fixing and is a completely dry recording, and it requires a mechanical operation for printing. It is used for printers, digital copiers, facsimiles, etc. as a highly reliable recording device with low noise. However, in either case, there is the inconvenience that clear recording cannot be performed unless a dedicated recording paper is used. Therefore, a recording apparatus using an intermediate transfer medium has been devised so that clear recording can be performed on plain paper without using a dedicated recording paper.

However, in the recording apparatus having the above configuration, the relationship between the temperature of the intermediate transfer medium 1 and the energizing energy to the thermal head 2 for obtaining a predetermined recording density is as shown in FIG. The energization energy tends to increase as the temperature of the intermediate transfer medium 1 decreases. This is because the formation of the ink image 3A utilizes the heat generated by the heating element 2A of the thermal head 2, and if the temperature of the intermediate transfer medium 1 is low, the intermediate transfer medium 1 loses heat for forming the ink image 3A. This is because. Therefore, when the environmental temperature is low and the intermediate transfer medium 1 is low, for example, about twice as much energizing energy as that at room temperature is required, and the energizing energy at low temperature increases.

With the above-described structure, the present invention can heat the intermediate transfer medium by the heat of the pressing roller without newly providing heating means such as a heater. The temperature of the intermediate transfer medium can be maintained at a predetermined temperature by controlling contact / separation of the pressing roller with respect to the intermediate transfer medium. Therefore, if the temperature of the intermediate transfer medium is kept at a predetermined temperature even in a low temperature environment, the heat taken by the intermediate transfer medium at the time of ink image formation can be reduced and the energizing energy to the thermal head can be reduced. Further, in a low temperature environment, the temperature drop of the thermal head itself also causes an increase in energization energy. Therefore, in a low-temperature environment, the temperature of the intermediate transfer medium is raised above that at room temperature to increase the thermal offset for ink image formation, thereby suppressing the increase in energizing energy even when the thermal head is cold.

Since the pressing roller 8 needs to soften the ink image 3A on the intermediate transfer medium 1 through the recording paper 7, it is heated and kept at a temperature of about 130 ° C., for example. Normally, the pressing roller 8 is separated from the intermediate transfer medium 1 and does not directly transfer the heat to the intermediate transfer medium 1.
In this embodiment, the heat of the pressure roller 8 is positively utilized by bringing the pressure roller 8 into contact with the intermediate transfer medium 1 in order to heat the intermediate transfer medium 1. Since the recording image may be disturbed during the recording operation (when the ink image 3A is formed on the intermediate transfer medium 1 or when the ink image 3A is transferred on the recording sheet 7), the pressing roller 8 should be brought into direct contact with the intermediate transfer medium 1. Therefore, the pressing roller 8 cannot be used during recording without recording.
Is brought into contact with the intermediate transfer medium 1 to heat the intermediate transfer medium 1. When the pressing roller 8 is brought into contact with the intermediate transfer medium 1, the heat of the pressing roller 8 flows into the intermediate transfer medium 1 and the temperature of the intermediate transfer medium 1 rises. The intermediate transfer medium 1 is rotationally driven in the direction of arrow X in order to make the temperature of the intermediate transfer medium 1 uniform. If the pressing roller 8 is kept in contact with the intermediate transfer medium 1, the intermediate transfer medium 1 will be heated to a temperature close to the temperature of the pressing roller 8, so the pressing roller 8 is separated from the intermediate transfer medium 1 at a predetermined temperature. There is a need to. Therefore, the thermistor 11, the separation / contact control circuit 12, and the separation / contact control mechanism 13 are used. First, the temperature of the intermediate transfer medium 1 is detected by the thermistor 11. Separation control circuit 12
Compares the temperature of the intermediate transfer medium 1 detected by the thermistor 11 with a predetermined temperature, and if the temperature of the intermediate transfer medium 1 is lower, the pressing roller 8 is intermediately transferred through the separating / contacting mechanism 13. Press on the medium 1. When the temperature of the intermediate transfer medium 1 rises and the temperature of the intermediate transfer medium 1 becomes higher than a predetermined temperature, the separation / contact control circuit 12 causes the separation / contact control mechanism 13 to operate.
The pressing roller 8 is separated from the intermediate transfer medium 1 via the. By repeating this operation, the temperature of the intermediate transfer medium 1 can be kept at a predetermined temperature.

Since the intermediate transfer medium 1 can be kept at a predetermined temperature regardless of the ambient environment temperature by the above-mentioned method, the amount of heat taken by the intermediate transfer medium 1 when the ink image 3A is formed does not change, and the thermal head 2 in the low temperature environment. It does not happen that the energizing energy to the is increased.

As described above, according to the present embodiment, the temperature of the intermediate transfer medium 1 is detected by the thermistor 11, and the separation / contact control circuit 12 controls the separation / contact control mechanism 13 so that the detected value becomes equal to a predetermined temperature. The pressure roller 8 is separated from and brought into contact with the intermediate transfer medium 1 via the intermediate transfer medium 1, and the intermediate transfer medium 1 is always heated and kept at a predetermined temperature regardless of the ambient environment temperature. Even if the environment is low, the energizing energy does not increase. Further, as a result, it is not necessary to control the energizing energy depending on the temperature of the intermediate transfer medium 1, so that the energizing energy control method and the circuit configuration can be simplified.

In the present embodiment, the intermediate transfer medium 1 is always kept at a predetermined temperature regardless of the environmental temperature. However, the thermistor 10 detects the temperature of the surrounding environment, and when the environmental temperature is low, the intermediate transfer is performed. A configuration in which the temperature of the medium 1 is further increased is also conceivable. This is because the temperature of the thermal head 2 itself is deeply related to the energization energy to the thermal head 2, and when the temperature of the thermal head 2 is low, the energization energy tends to increase. Therefore, by increasing the temperature of the intermediate transfer medium 1 in a low temperature environment, it is possible to increase the thermal offset amount with respect to the formation of the ink image 3A and further suppress the energizing energy. Further, since heat is used also when the ink image 3A formed on the intermediate transfer medium 1 is transferred to the recording sheet 7, the transfer becomes easy if the temperature of the intermediate transfer medium 1 is high. However, since the temperature of the intermediate transfer medium 1 is not constant, the energizing energy to the thermal head 2 needs to be controlled according to the environmental temperature or the temperature of the intermediate transfer medium 1. The intermediate transfer medium 1
As a method of increasing the temperature of 1, there is a method of simply lengthening the contact time of the pressure roller 8 and a method of increasing the heat retention temperature of the pressure roller 8.

Although the intermediate transfer medium 1 has a roller shape based on the metal tube 1B, a silicone rubber layer 1A is formed on a base such as a polyimide film to have a belt shape, and the pressing roller 8 is provided inside the intermediate transfer medium. A configuration in which the intermediate transfer medium is heated from the inside is also conceivable. At this time, a member that receives pressure from the pressure roller 8 is required at a position facing the pressure roller 8 with the intermediate transfer medium interposed therebetween.

Further, as a method of heating and keeping the thermal head 2 warm, a method of bringing the thermal head 2 into contact with the intermediate transfer medium 1 can be considered. As described above, the energizing energy to the thermal head 2 is also affected by the temperature of the thermal head 2 and is effective in reducing the energizing energy in a low temperature environment.

As described above, according to the present invention, the heated pressing roller is brought into contact with or separated from the intermediate transfer medium and the heat of the pressing roller flows into the intermediate transfer medium without newly providing a heating means such as a heater. By heating and maintaining the temperature of the intermediate transfer medium in this manner, the amount of heat flowing out to the intermediate transfer medium at the time of ink image formation in a low temperature environment can be reduced and the energizing energy to the thermal head necessary for ink image formation can be reduced. .
