A method of transferring this mobile dye to a dye fixing material with a mordant using a solvent such as water, a method of transferring it to a dye fixing material using a high boiling point organic solvent, a method of transferring this mobile dye to a dye fixing material using a hydrophilic thermal solvent incorporated in the dye fixing material A method in which the mobile dye is heat-diffusible or sublimable and is transferred to a dye-receiving material such as a support has been proposed. (U.S. Patent No. 4.463.079, U.S. Patent No. 4.474867, U.S. Patent No. 4,478,927, U.S. Patent No. 4507.380, JP-A-58-149046, U.S. Pat. No. 58-149047

An image recording apparatus has been proposed in which an image-receiving material is brought into close contact with a heat-developable photosensitive material after heat development, and the image is sent to a transfer section, where the image is thermally transferred to the image-receiving material.
そして、画像形成溶媒を塗布する塗布装置として、例え
ば、水槽内に収容した画像形成溶媒中に記録材料を浸漬
しながら搬送し、一対のスクイズローラ間に前記記録材
料を挟持し、膨潤した記録材料から余分な画像形成溶媒
を掻き取る構成のものがある。Then, as a coating device for applying the image forming solvent, for example, the recording material is conveyed while being immersed in the image forming solvent stored in a water tank, the recording material is held between a pair of squeeze rollers, and the recording material is swollen. Some devices are designed to scrape off excess image forming solvent.
前記画像形成溶媒の上述の記録材料への膨潤は、画像転
写の促進と良好な発色を行うためのものである。そして
、記録材料への膨潤量は前記画像形成溶媒の温度に大き
く左右されるので、従来は、水槽内に加熱器（ヒータ）
を設（す、画像形成溶媒を所望の温度に制御し、記録材
料への膨潤量を安定化している。Swelling of the image forming solvent into the recording material is for promoting image transfer and good color development. Since the amount of swelling of the recording material greatly depends on the temperature of the image forming solvent, conventionally a heater is installed in the water tank.
The image forming solvent is controlled at a desired temperature to stabilize the amount of swelling of the recording material.
このため、画像形成溶媒が水槽から常に蒸発しており、
水槽内の溶媒水位が下がり、記録材料の画像形成溶媒内
移動距離が短くなり、膨潤量が低下する結果となってい
る。Because of this, the imaging solvent is constantly evaporating from the water bath.
The water level of the solvent in the water tank is lowered, and the distance that the recording material moves within the image forming solvent is shortened, resulting in a decrease in the amount of swelling.
また一方で、画像記録動作を継続すると、換言すれば記
録材料を繰り返し浸漬していると、画像形成溶媒が次第
に減少し、上述と同様に画像形成溶媒の膨潤量が低下す
る結果となる。On the other hand, if the image recording operation continues, in other words, if the recording material is repeatedly immersed, the image forming solvent will gradually decrease, resulting in a decrease in the amount of swelling of the image forming solvent as described above.
本発明の目的は、この問題を解決することにあり、水槽
内の画像形成溶媒の減少に対して適応量を補充すること
のできる塗布装置及び補充方法を提供することにある。An object of the present invention is to solve this problem, and to provide a coating device and a replenishment method that can replenish an appropriate amount of image forming solvent in a water tank when the amount decreases.

補充方法によって達成される。[Means and effects for solving the problem] The above-mentioned object of the present invention is to transport a recording material while immersing it in an image forming solvent controlled to a desired temperature by a heater in a water bath, and to remove the swollen recording material. A solvent replenishment method in image forming solvent application in which excess image forming solvent is scraped off between a pair of squeeze rollers, and the amount of solvent evaporated from a water tank per unit time during non-application time is set in advance. outputs a signal corresponding to the amount of solvent reduced from within the water tank based on the number of applied recording materials and the preset amount of solvent applied per area of one recording material, and An image-forming solvent replenishment method that detects that the solvent has reached a predetermined reduction amount in a water tank based on a signal corresponding to the amount and a signal corresponding to the solvent reduction amount, and replenishes the solvent in the water tank by the predetermined reduction amount. achieved by

録材料の単位面積当たりの溶媒塗布量もほぼ一定である
ので、上述のように塗布記録材料数と記録材料１枚の面
積当たりの予め設定された溶媒塗布量とをもとに、溶媒
塗布時の水槽内からの溶媒減少量を決定する。That is, since the image forming solvent evaporates almost constantly from the water tank, the amount of evaporation is determined based on a preset value and elapsed time, without using any means to directly measure the amount of evaporation, and furthermore, the amount of evaporation is determined based on a preset value and elapsed time. Since the amount of solvent applied per unit is almost constant, the amount of solvent applied from inside the aquarium during solvent application is determined based on the number of applied recording materials and the preset amount of solvent applied per area of one recording material as described above. Determine the amount of solvent reduction.
そして、上述の溶媒蒸発量と溶媒減少量とにより、水槽
内からの溶媒減少量が算出でき、これが所定の溶媒減少
量となったとき、該所定減少量分の溶媒を補充するもの
である。Then, the amount of solvent decreased from inside the aquarium can be calculated from the above-mentioned amount of solvent evaporation and amount of decrease in solvent, and when this reaches a predetermined amount of decrease in solvent, the solvent for the predetermined amount of decrease is replenished.
以上のように、水槽内の画像形成溶媒の減少に対して適
応量を補充することができる。As described above, an adaptive amount can be replenished in response to a decrease in the imaging solvent in the water tank.
