イクロフイルム等に用いられている。 Unlike photographic films that use silver salt photographic materials as photoreceptors, electrophotographic materials take advantage of the characteristic that they can be reused by cleaning them after development and before fixing, regardless of whether they are exposed or not. ,
A long roll film is used as a photosensitive material, and an image is recorded partially by charging, exposing, developing, and fixing, and the resulting image is used for purposes such as projection, along with the unrecorded portions. This is used in microfilm, etc., where new records are added to the unrecorded areas after recording.

（以下スクイズと称す）を行なう必要がある。 Among electrophotographic devices using microfilm as described above, in so-called wet-type electrophotographic devices that develop electrostatic latent images using liquid toner, each frame is
Charging, exposure, development, drying and fixing are performed, so
During the development process, it is preferable that toner not overflow or ooze out of areas other than the area of the photosensitive material to be processed, and excess developer solution should be removed before the photosensitive material is separated from the developing section and transferred to another processing section. It is necessary to drain the liquid (hereinafter referred to as "squeeze") to remove it.

のである。 Here, a conventional wet-type electrophotographic apparatus using a vacuum pump will be described with reference to FIG. As shown in the figure, a body 1 of this type of developing head is equipped with a mask 2, and this mask 2 has an opening 2a with a width corresponding to one frame of the photosensitive material 3, and an opening end of the opening 2a. 2b is in contact with the photosensitive material 3. As a result, the photosensitive surface 3a of one frame of the photosensitive material 3 faces the opening 2a, and a predetermined latent image is developed by spraying the liquid toner 4 onto the photosensitive surface 3a through the opening 2a. Following this development, it is necessary to squeeze the toner 4 adhering to the photosensitive surface 3a, and this squeezing is similarly performed by blowing a gas such as air onto the photosensitive surface 3a through the opening 2a.
Therefore, it is necessary to transport the liquid toner 4 and gas (air in this example) to the opening 2a, but this transport involves sucking up the toner 4 stored in the tank 5 with the vacuum pump 6 and opening the valve 7. When opened, air is similarly sucked in from the air by the vacuum pump 6. That is, the water flows from the tank 5 to the inside of the body 1 through the opening 2a.
A flow path 8 passes through the vacuum pump 6 and returns to the tank 5, and a flow path 8 passes through the valve 7 from the end open to the atmosphere to the inside of the body 1, and connects to the flow path 8 upstream of the opening 2a. A flow path 9 that merges is formed. In FIG. 1, reference numeral 10 denotes a developing electrode, which faces the photosensitive surface 3a to increase the developing speed and obtain a good image with little edge effect.

がある。 Thus, the developing head of this type of electrophotographic apparatus develops the photosensitive surface 3a by spraying the toner 4,
After squeezing, the process proceeds to the next drying and fixing process, but since the developing head uses a vacuum pump 6 as a conveyance system for the toner 4 and squeeze gas, the structure of this part is complicated. It has become expensive. Alternatively, a system in which the toner is force-fed using a liquid pump or the like without using a vacuum pump can be considered, but the space between the photosensitive surface 3a in the developing area and the developing electrode 10 is usually quite narrow, and liquid resistance occurs due to the viscosity of the toner. easily enters the gas transport line. At this time, if toner gets into the gas conveying pump, it will cause trouble, and even if the toner just gets inside the tube, when the gas conveying pump starts operating, the toner that has gotten into the tube will be blown out into the developing chamber. The disadvantage is that it lowers the

向へのみの流れを許容する一方向弁で良い。 Embodiments of the present invention will be described in detail below based on the drawings. As shown in FIG. 2, the body 11 of the developing head of this embodiment is also provided with a mask 12 similar to the prior art, and this mask 12 has a wide area corresponding to the frame of the photosensitive material 13 to be developed. It has an opening 12a, and its opening end 12b is in contact with the photosensitive material 13. As a result, photosensitive material 1
The photosensitive surface 13a for one frame of 3 faces the opening 12a, and the liquid toner 14 is applied through the opening 12a.
A predetermined latent image is developed by spraying the same, and after this development is completed, the photosensitive surface 13 is
Squeeze by blowing air onto a. The first flow path 18 is connected to the tank 1 in which the toner 14 is stored.
5 is open at one end, and is used exclusively to transport toner 14 pumped up by a pump 16 interposed in the middle. As the pump for pumping the toner, known pumps such as an emperor pump, gear pump, and vane pump can be used. On the other hand, the second
The flow path 19 has an air pump 2 attached to its end.
0 exclusively conveys the air sucked in. The valve 17 is provided closer to the opening 12a than the air pump 20 in the second flow path 19 through which squeezing air flows. Thus, the toner 14 is supplied directly to the developing head via the first flow path 18 and
may be a one-way valve that allows flow only from the second flow path 19 toward the developing head (opening 12a).

１２ａを介して感光面１３ａに吹き付けられる。 In an embodiment having such a valve 17, when the toner 14 is pumped by driving the pump 16, the valve 1
7 closes the second flow path 19, all of the toner 14 is sprayed onto the photosensitive surface 13a through the opening 12a without going around to the second flow path 19.

を生起するとともにスクイズ効率を低下させる。 Incidentally, if the toner 4 and air transport system in the developing head shown in FIG. The toner 4 flows around and accumulates between the intersection with the flow path 8 and the valve 7, and in the next squeeze step, this amount of toner 4 mixed with air is blown onto the photosensitive surface 3a, causing stains on the photosensitive surface 3a. At the same time, the squeezing efficiency is reduced.

ポンプ２０の駆動によるスクイズ工程では弁１７

ａを介して感光面１３ａに吹き付けられる。 On the other hand, in the squeeze step by driving the air pump 20 following the developing step in this embodiment, the valve 17
opens the second flow path 19, so air flows through the opening 12.
The light is sprayed onto the photosensitive surface 13a through a.

事ができる。 At this time, if the valve 17 is closed when the pump 16 for feeding the developer is operated, air is accumulated in the second flow path 19, so the toner 14 does not reach the valve 17 and is squeezed by the toner 14. Since the number of piping parts through which the air flows can be reduced, the above-mentioned drawbacks such as staining of the photosensitive surface 13a during squeezing can be further reduced.

しても良い。 In the above embodiment, the air pump 20 is used as a means for pumping the gas, but similar functions and effects can be obtained even if a compressed gas cylinder or a liquefied gas cylinder is connected to the second flow path 19. In addition to air, carbon dioxide gas, chlorofluorocarbon gas, propane gas, butane gas, etc. can be used as the gas for squeezing at this time. Further, since the photosensitive surface 13a is disposed vertically or nearly vertically as shown in FIG. 2, the liquid contained in the toner 14 falls to the lower part of the photosensitive surface 13a due to its own weight. Therefore, the squeezing air may be blown toward the lower part.

According to the present invention, since the toner and the squeeze gas are fed under pressure, the structure is not only simplified, but also the toner can be prevented from flowing into the second flow path, which is a flow path dedicated to gas conveyance, by a valve. At this time,
Since only one one-way valve is required, the structure can be simplified and costs can be reduced in this respect as well.
