【発明の詳細な説明】
[産業上の利用分野]
この発明は、浸漬塗布方法によって導電性基体上に感光
層を形成する感光体の製造方法、特に、感光層を電荷発
生層と電荷輸送層とに分離させた機能分離型感光体の製
造方法に関するものである。Detailed Description of the Invention [Industrial Application Field] This invention relates to a method for producing a photoreceptor in which a photoreceptor layer is formed on a conductive substrate by a dip coating method, and in particular, a method for manufacturing a photoreceptor in which a photoreceptor layer is formed by forming a photoreceptor layer on a charge generation layer and a charge transport layer. The present invention relates to a method for manufacturing a functionally separated photoreceptor.
[従来技術及びその問題点]
一般に電子写真の方式としては、感光体の感光層表面に
帯電、露光を行って静電潜像を形成し、これを現像剤で

電潜像を転写紙上に転写し、転写紙上の静電潜像を現像
・定着する潜像転写方式等が知られている。[Prior art and its problems] Generally, in electrophotography, the surface of the photosensitive layer of a photoreceptor is charged and exposed to form an electrostatic latent image, and this is developed with a developer to make it visible. A direct method in which a visible image is directly fixed on a photoreceptor to obtain a copy image, and a powder image method in which a visible image on a photoreceptor is transferred onto a transfer paper such as paper and the transferred image is fixed to obtain a copy image. A transfer method or a latent image transfer method is known in which an electrostatic latent image on a photoreceptor is transferred onto a transfer paper, and the electrostatic latent image on the transfer paper is developed and fixed.
従来、このような電子写真に使用する感光体において、
感光層を形成する場合には、その光導電性材料として、
セレン、硫化カドミウム、酸化亜鉛等の無機系光導電性
材料を用いることが知られている。Conventionally, in photoreceptors used for such electrophotography,
When forming a photosensitive layer, as the photoconductive material,
It is known to use inorganic photoconductive materials such as selenium, cadmium sulfide, and zinc oxide.
これらの光導電性材料は、暗所で適当な電位に帯電でき
ること、暗所で電荷の逸散が少ないこと、あるいは光照
射によって速やかに電荷を逸散できることなどの数多く
の利点をもっている反面、次のような各種の欠点を有し
ている。These photoconductive materials have many advantages, such as being able to be charged to an appropriate potential in the dark, having little charge dissipation in the dark, and being able to quickly dissipate charge when irradiated with light. It has various drawbacks such as:
例えば、セレン系感光体では、製造コストが高く、また
熱や機械的な衝撃に弱いため取り提いに注意を要する。For example, selenium-based photoreceptors are expensive to manufacture and are susceptible to heat and mechanical shock, so care must be taken when handling them.
また、硫化カドミウム系感光体では、多漏の環境下で安
定した感度が得られない点や、増感剤として添加した色
素がコロナ帯電による帯電劣化や露光による光退色を生
じるため長期にわたって安定した特性を与えることがで
きない欠点を有している。In addition, cadmium sulfide photoreceptors do not provide stable sensitivity in environments with high leakage, and the dye added as a sensitizer causes charge deterioration due to corona charging and photobleaching due to exposure to light, so it is difficult to obtain stable sensitivity over a long period of time. It has the disadvantage of not being able to provide specific characteristics.
また、従来においては、ポリビニルカルバゾールをはじ
めとする各種の有機光導電性ポリマーを感光層の形成に
用いることも検討されてきた。これらのポリマーは、前
述の無機系光導電性材料に比べて成膜性、軽量性などの
点で優れているが、未だ十分な感度、耐久性および環境
変化による安定性の点で無機系光導電性材料に比べ劣る
という欠点があった。Furthermore, in the past, it has been considered to use various organic photoconductive polymers such as polyvinylcarbazole to form the photosensitive layer. Although these polymers are superior to the aforementioned inorganic photoconductive materials in terms of film formability and light weight, they still lack sufficient sensitivity, durability, and stability against environmental changes. It had the disadvantage that it was inferior to conductive materials.
そこで、これらの感光体における上記のような欠点を解
決するため、近年において種々の研究開発が行われ、導
電性支持体上に電荷発生層と電荷輸送層とを積層してな
る機能分離型の積層感光体や、電荷発生機能と電荷輸送
機能を兼ねた光導電層を支持体上に積層してなる単層型
の感光体が提案されるようになった。Therefore, in order to solve the above-mentioned drawbacks of these photoreceptors, various research and developments have been conducted in recent years, and a functionally separated type photoreceptor consisting of a charge generation layer and a charge transport layer laminated on a conductive support has been developed. Laminated photoreceptors and single-layer photoreceptors in which a photoconductive layer having both charge generation and charge transport functions is laminated on a support have been proposed.
特に、前者の機能分離型の積層感光体は、感光層の形成
に使用する物質の選択範囲が広く、帯電特性、感度、残
留電位、繰り返し特性、耐刷性等の電子写真特性におい
て、最良の物質を組み合わせることにより高性能な感光
体を提供することができるため、このような感光体が広
く利用されるようになった。In particular, the former function-separated type laminated photoreceptor has a wide selection of materials used to form the photosensitive layer, and has the best electrophotographic properties such as charging characteristics, sensitivity, residual potential, repeatability, and printing durability. Since high-performance photoreceptors can be provided by combining materials, such photoreceptors have come to be widely used.
そして、このような機能分離型積層感光体を製造するに
あたっては、導電性支持体を塗布液中に浸漬させた後、
この塗布液中から引き上げて、塗布液を導電性支持体上
に塗布するという浸漬塗布方法が、生産性および製造コ
スト面で優れているため、一般に用いられている。In manufacturing such a functionally separated laminated photoreceptor, after immersing the conductive support in a coating solution,
A dip coating method in which the coating solution is lifted from the coating solution and applied onto the conductive support is generally used because it is excellent in terms of productivity and manufacturing cost.
このような浸漬塗布方法によって導電性支持体上に感光
層を形成する場合、その膜厚は塗布液の濃度、粘度及び
支持体の引き上げ速度等によって定まり、塗布液の濃度
や粘度が高く、また引き上げ速度が速いはど膜厚が厚く
なることが知られている。ここで、導電性支持体の引き
上げ速度が速すぎると、塗膜が厚くなって乾燥するまで
の時間が長くなり、液だれをおこし、むら、ができたり
、導電性支持体の上部と下部の膜厚の差が大きくなる一
方、導電性支持体の引き上げ速度が遅いと、生産性が悪
く、また乾燥時において、湿度によって生じる白化現象
が起こりやすくなる。When forming a photosensitive layer on a conductive support by such a dip coating method, the film thickness is determined by the concentration and viscosity of the coating solution, the speed of pulling up the support, etc. It is known that the faster the pulling speed, the thicker the film becomes. If the speed at which the conductive support is pulled up is too fast, the coating film will become thick and take a long time to dry, resulting in dripping, unevenness, and If the difference in film thickness increases while the pulling speed of the conductive support is slow, productivity will be poor and whitening caused by humidity will likely occur during drying.
このように、浸漬塗布方法においては、導電性支持体の
上下において膜厚差が出やすく、また乾燥条件等により
液だれや膜厚むらを起こしたり、白化現象が生じたりし
て画像に悪影響を与えるという問題があり、特に、機能
分離型の積層感光体においては、電荷輸送層の塗工精度
が、画像の品質や耐刷性等に大きな影響を与えるため、
その塗布液の種類や支持体の引き上げ速度等が大きな問
題となった。In this way, in the dip coating method, differences in film thickness tend to occur between the upper and lower sides of the conductive support, and depending on the drying conditions, liquid dripping, uneven film thickness, and whitening phenomenon occur, which adversely affects the image. In particular, in functionally separated laminated photoconductors, the coating accuracy of the charge transport layer has a large impact on image quality and printing durability.
The type of coating liquid and the pulling speed of the support became major problems.
このため、従来においても、このような浸漬塗布方法に
おいて使用する塗布液の溶媒や支持体の引き上げ速度等
について種々検討された。For this reason, in the past, various studies have been made regarding the solvent of the coating liquid used in such dip coating methods, the lifting speed of the support, and the like.

層を形成するようにしたのである。[Means for Solving the Problems] In the method for producing a photoreceptor according to the present invention, a photosensitive layer is formed on a support by a dip coating method, in particular, a charge transport layer is formed in a functionally separated laminated photoreceptor. In this case, the organic solvent used in the coating liquid is a mixture of at least two types of solvents selected from a cyclic ether solvent and a cyclic ketone solvent, and the viscosity of the coating liquid is 25%.
The photosensitive layer was formed by adjusting the speed to be 0 to 500 cps and at a rate of 30 to 80 cps per minute.

布液の粘度がほとんど変化するということがない。When a mixed solvent containing two or more of these solvents is used in the coating solution, the solubility of charge transport substances, resins, etc. is significantly improved, and the viscosity stability of the coating solution is improved. Therefore, even when stored for a long time, the viscosity of the coating liquid hardly changes.

抑制されるようになる。In addition, the viscosity of the coating liquid using such a solvent is 250~
By adjusting the speed to 500 cps and pulling the support from this coating solution at a pulling rate of 30 to 80/min, a photosensitive layer with a uniform thickness is formed on the support, and the photoreceptor Image stability and printing durability are improved, and black spots and the like on blank areas that occur when reverse development is performed in a laser printer or the like are suppressed.

くなりすぎ、乾燥むらを生じたり、塗膜にボイドが発生
したりして画像欠損が生じやすくなるためである。The reason why the viscosity of the coating solution is adjusted to 250 to 500 cps is because if the viscosity is lower than 250 cps, there will be a large amount of liquid dripping when the support is pulled up. While the thickness difference increases,
If the viscosity is higher than 500 cps, the coating speed becomes too slow, causing uneven drying, voids in the coating film, and image defects.
