真用感光材料の製法に関する。Detailed Description of the Invention (Technical Field) The present invention relates to a method for producing a photosensitive material for electrophotography, more specifically,
The selenium-based electrophotographic light-sensitive materials used in electrophotographic devices contain the halogen contained therein almost uniformly in each manufacturing unit of this 10-gun-sized light-sensitive material. Regarding the manufacturing method.

もよく知られている。(Prior art) As is well known, an electrostatic image of an original is formed on a photoreceptor, this electrostatic latent image is developed with toner into a visible image, and this visible image is transferred onto a recording sheet. In a dry type electrophotographic apparatus in which processes are repeated, amorphous selenium is generally used as a photosensitive material for the photoreceptor. It is also well known that amorphous selenium is one of the substances that exhibits excellent photoconductive performance.

ルファス−セレンが結晶化してしまうという欠点があっ
た。However, as is well known, photoreceptors using amorphous selenium have low photosensitivity, making it difficult to reproduce the No.-7 tone of the original image on the recording sheet, and also because they are not sensitive to long wavelength light. However, red and orange colors are difficult to reproduce on the recording sheet, and the amorphous selenium, which should originally be amorphous, crystallizes because it is thermally unstable.
そこで、上述のような欠点を除去するために、従来テル

いは同じく砒素を添加して耐熱性を改善するというよう
な手段がとられていた。Therefore, in order to eliminate the above-mentioned drawbacks, conventional methods have been taken such as adding tellurium to the selenium to improve the sensitivity, or similarly adding arsenic to improve the heat resistance. .
しかし、上述の手段を採ると、確かに感度や耐熱性は改

テルル等に添加する手段が有効であるとされ、従来も種
々の添加手段が提案されてきた。However, when the above-mentioned measures are taken, although sensitivity and heat resistance are certainly improved, there are drawbacks such as side effects. In other words, among the above drawbacks, the most serious one is that it causes a so-called background smudge phenomenon in which areas that should originally be copied on a white background become a thin black background. This would be a fatal flaw for the electronic 4-motor device. The cause of this scumming is the accumulation of residual potential on the photoreceptor, and in order to prevent the accumulation of this residual potential, it is effective to add a small amount of halogen to the tellurium or the like. Therefore, various means of addition have been proposed in the past.

ある。The main conventional means for this is, for example, when adding a trace amount of halogen to a selenium/tellurium alloy or a selenium/tellurium/arsenic alloy, the dissolved selenium/tellurium/arsenic
In tellurium alloys or selenium/tellurium/arsenic alloys,
There is a method for adding selenium/halogen containing halogen, which is charged and cooled by an appropriate means.

次の工程である蒸着工程等に用いねばならなかった。However, when the above-mentioned addition means was used, it was necessary to constantly check whether the above-mentioned trace amount of halogen was added at a predetermined ratio. In other words, since the halogen content varies depending on the production unit of the selenium/tellurium alloy, etc., each time the selenium/tellurium alloy, etc. mentioned above is produced, it is necessary to use an appropriate halogen analyzer.
Analyze the concentration of added halogen and select only the selenium/tellurium alloys that have the target concentration.
This had to be used in the next step, such as a vapor deposition step.

金等が溶解する条件によって、様々であるために、上記
ハロゲンの含有量がバラツクと考えられている。As mentioned above, the reason for the variation in the halogen content in selenium/tellurium alloys, etc. is that when selenium/halogen base metal is added to the melted selenium/tellurium alloy, the selenium and halogen that have been combined are This is because the bond is broken and the free halogen scatters into the outside air, and the rate of this scattering varies depending on the conditions in which selenium/halogen base metal etc. are dissolved. The content is thought to vary.
