【発明の詳細な説明】
電子写真複写機はその基体の周面に感光性材料
を塗布して製作するが、この塗布方法には種々の
方法がある。基体を塗布液中に浸漬するのもその
うちの一つであるが、本発明はこの浸漬塗布方法
に関するものである。DETAILED DESCRIPTION OF THE INVENTION An electrophotographic copying machine is manufactured by coating the peripheral surface of its base with a photosensitive material, and there are various methods for this coating. One such method is to immerse the substrate in a coating solution, and the present invention relates to this dip coating method.
前記浸漬塗布は、塗布液の溜りに基体を浸漬す
るものであるから、塗布液溜りの液面に溶媒の蒸
発による皮膜が生じ、これが基体の周面に付着す
る欠点がある。 Since the dip coating method involves immersing the substrate in a pool of coating liquid, it has the disadvantage that a film is formed on the surface of the coating liquid pool due to evaporation of the solvent, and this film adheres to the peripheral surface of the substrate.
本発明は、前記欠点を解消することを目的とす
るものであつて、浸漬の都度、塗布液をオーバー
フローさせることを特徴とするものである。 The present invention aims to eliminate the above-mentioned drawbacks, and is characterized in that the coating liquid overflows each time it is immersed.
次に本発明を図示の実施例によつて説明する。 Next, the present invention will be explained with reference to illustrated embodiments.
１は円筒形の容器であつて、ドラム状感光体基

接続されている。 A cylindrical container 1 has an inner diameter slightly larger than the outer diameter of the drum-shaped photoreceptor substrate 6 and a depth larger than the axial length of the drum-shaped photoreceptor substrate 6. An annular gutter 2 is provided on the outer periphery of the upper edge of the container 1, and is connected to a waste liquid tank (not shown) via a pot 3. The bottom of the container 1 is connected to a replenishment tank (not shown) via a pot 4.

フローに際し、塗布液５の液面に生じていた皮膜

る。 The pot 4 is opened and a predetermined amount of the coating liquid 5 is poured into the container 1 as shown in FIG. 2a. Next, the drum-shaped photoreceptor substrate 6 with both ends closed is inserted into the container 1 as shown in FIG. 2b. The coating liquid 5 is pushed away by the drum-shaped photoreceptor substrate 6, the liquid level rises, and the entire circumference of the drum-shaped photoreceptor substrate 6 is immersed.
As a result of the further rise in the liquid level, the liquid overflows from the upper edge of the container 1 and flows into the gutter 2. At the time of this overflow, the film formed on the surface of the coating liquid 5 also flows out. Of course, floating debris is also discharged.
ドラム状感光体基体６を引上げると塗布が完了
するが、次のドラム状感光体基体を浸漬する前
に、コツク４を開いて、塗布液５の補給を行な
う。この補給量は、ドラム状感光体基体６に塗布
された分よりも余分にし、次回もオーバーフロー
が生じるようにする。 Coating is completed when the drum-shaped photoreceptor substrate 6 is pulled up, but before dipping the next drum-shaped photoreceptor substrate, the pot 4 is opened and the coating liquid 5 is replenished. The amount of replenishment is made to be in excess of the amount coated on the drum-shaped photoreceptor substrate 6, so that overflow will occur next time as well.
本発明は以上のように浸漬の都度、オーバーフ

面が得られる。 As described above, the present invention generates an overflow each time it is immersed, so that no film remains on the surface of the coating solution, and there is no risk of it adhering to the peripheral surface of the drum-shaped photoreceptor substrate, resulting in a smooth coating. A coated surface is obtained.
