Description

本発明は、複写機、プリンタ、ファクシミリ等の電子写真式の画像形成装置に使用される一成分式の現像装置において粉体トナーを担持する手段として利用されるトナー担持体、トナー担持体、現像装置、及び画像形成装置に関する。 The present invention relates to a toner carrier used as a means for carrying powder toner in a one-component developing device used in an electrophotographic image forming apparatus such as a copying machine, a printer, and a facsimile, a toner carrier, and development. The present invention relates to an apparatus and an image forming apparatus.

近年、デジタルファブリケーションという印刷技術を応用した物作り技術が注目されており、その代表的なものとして、スクリーン印刷法とインクジェット法を応用した配線形成技術がある。
スクリーン印刷法は、一種の孔版印刷であり、配線パターンが形成された版を用いて導電性ペーストを基板に印刷する方法である。スクリーン印刷法に代表されるような有版印刷法は、版を必要とするため、少量多品種の生産には向かないが、大量生産では低コスト化が見込める方法である。しかし、スクリーンの線径をあまり細くすることができないため、線幅やピッチの細かいものには対応できないという問題がある。また、印刷対象物（基体）が円筒体である場合、円筒形状の直径（＝周長）に僅かなばらつきがあると、印刷のつなぎ目部でパターンの位置精度が悪くなると言った不具合が生じることも、有版印刷法特有の問題点である。
インクジェット法は、インクジェットヘッドを用いて導電性インクを基板にオンデマンドに塗布する方法である。マスクレスのため少量多品種の生産には向いているが、配線パターンの配線幅やピッチが細かいものが要求された場合、他の印刷方法と比較して、印刷時間が長くなり、加工コストが高くなるという問題や、大量生産や大面積化に向かないという問題点がでてくる。
印刷技術以外の配線形成方法としては、従来のフォトリソグラフィー法がある。フォトリソグラフィー法は、絶縁基板に銅メッキを施し、その上にフォトレジストを塗布して、フォトマスクを介して露光、現像してレジストパターンを形成し、銅エッチングにより配線パターンを形成するものである。対象物（基体）が円筒体である場合、曲面状の周面にフォトマスクを介した露光を行うことが難しくなるため、光源を目的の線幅まで絞込み、光源をＯＮ／ＯＦＦ制御しながら走査してレジストパターンを形成する技法が実施される。しかし、マスク露光とは異なり、光源を走査しながら少しずつレジストを硬化させるため、加工時間が長くなり、加工コストが高くなるという問題や、大量生産や大面積化に向かないという問題点がでてくる。また、銅電極をエッチングにより除去するため、材料使用量に無駄が生じたり、エッチング液や有機溶剤を使用することから環境負荷の高い製造方法になると言った問題点がある。 2. Description of the Related Art In recent years, a manufacturing technique that applies a printing technique called digital fabrication has attracted attention, and representative examples include a wiring formation technique that applies a screen printing method and an inkjet method.
The screen printing method is a kind of stencil printing and is a method of printing a conductive paste on a substrate using a plate on which a wiring pattern is formed. The plate printing method represented by the screen printing method requires a plate and is not suitable for the production of a small variety of products. However, the mass production can reduce the cost. However, since the screen diameter cannot be made very thin, there is a problem that it is not possible to deal with a fine line width or pitch. In addition, when the printing object (base) is a cylindrical body, there is a problem that if the cylindrical diameter (= peripheral length) varies slightly, the pattern position accuracy deteriorates at the joint portion of printing. Is a problem peculiar to the plate printing method.
The ink jet method is a method for applying conductive ink on a substrate on demand using an ink jet head. Although it is suitable for the production of a small variety of products because it is maskless, if a wiring pattern with a fine wiring width or pitch is required, the printing time will be longer and the processing cost will be lower than other printing methods. The problem of becoming high, and the problem that it is not suitable for mass production and large area come out.
As a wiring forming method other than the printing technique, there is a conventional photolithography method. In the photolithography method, copper plating is applied to an insulating substrate, a photoresist is applied thereon, exposure and development are performed through a photomask to form a resist pattern, and a wiring pattern is formed by copper etching. . When the object (base) is a cylindrical body, it becomes difficult to perform exposure through a photomask on a curved peripheral surface. Therefore, the light source is narrowed down to the target line width, and scanning is performed while controlling the light source ON / OFF. Then, a technique for forming a resist pattern is performed. However, unlike mask exposure, the resist is cured little by little while scanning the light source, which increases the processing time and processing costs, and is not suitable for mass production and large area. Come. In addition, since the copper electrode is removed by etching, there is a problem that the amount of material used is wasted, and that an etching solution or an organic solvent is used, resulting in a manufacturing method with a high environmental load.

次に、配線パターンの形成方法として、電子写真技術を応用した例を示す。
特許文献１の発明は、有機光導電層を有する電子写真感光体層を形成した基板に、（イ）該電子写真感光体を帯電させる工程、（ロ）該電子写真感光体を選択的に露光し、静電潜像を形成する工程、（ハ）該静電潜像に応じて該電子写真感光体にトナーを付着させ、パターンを形成する工程、（ニ）該パターンを形成した基板を焼成し、該有機光導電層を除去するとともにパターンを基板に直接固着させる工程を順次実施することによって、該トナーからなる所望のパターンを得ることを特徴としている。しかし、基板に有機光導電層が必要になることや、有機光導電層を除去する工程が必要になることから、工程が煩雑になり、加工コストが高くなるという問題点がある。
特許文献２の発明は、基板上の金属箔層をエッチングまたはリフトオフにより回路パターンを作製する方法において、パターンニングするためのレジストパターンを液体現像法で形成することを特徴としている。ここでの液体現像法では、予め帯電された感光体表面上に回路パターンに応じた電界分布潜像を形成し、レジスト部材を付着させて前記回路パターンに応じたレジスト像を形成し、基板上または前記金属箔層上に転写する。この方法は、マスクレスでレジストパターンを形成できるメリットがあるが、基板に金属を製膜する工程やエッチング工程があるため、工程数が多くなる。また、金属箔層をエッチングまたはリフトオフにより除去するため、材料使用量に無駄が生じることや、エッチング液や有機溶剤を使用することから環境負荷の高い製造方法になると言った問題点がある。 Next, an example in which electrophotographic technology is applied as a wiring pattern forming method will be described.
The invention of Patent Document 1 includes (a) a step of charging the electrophotographic photoreceptor on a substrate on which an electrophotographic photoreceptor layer having an organic photoconductive layer is formed, and (b) selectively exposing the electrophotographic photoreceptor. And (c) forming a pattern by attaching toner to the electrophotographic photosensitive member in accordance with the electrostatic latent image, and (d) firing the substrate on which the pattern is formed. In addition, the organic photoconductive layer is removed and the process of directly fixing the pattern to the substrate is sequentially performed to obtain a desired pattern made of the toner. However, since the organic photoconductive layer is required for the substrate and a process for removing the organic photoconductive layer is required, the process becomes complicated and the processing cost increases.
The invention of Patent Document 2 is characterized in that a resist pattern for patterning is formed by a liquid development method in a method for producing a circuit pattern by etching or lift-off of a metal foil layer on a substrate. In the liquid development method here, an electric field distribution latent image corresponding to a circuit pattern is formed on a surface of a pre-charged photoconductor, a resist member is attached, and a resist image corresponding to the circuit pattern is formed on a substrate. Alternatively, transfer onto the metal foil layer. Although this method has an advantage that a resist pattern can be formed without a mask, the number of steps increases because there are a step of forming a metal on a substrate and an etching step. In addition, since the metal foil layer is removed by etching or lift-off, there are problems that the amount of material used is wasted, and that an etching solution or an organic solvent is used, resulting in a manufacturing method with a high environmental load.

特許文献３の発明は、湿式の電子写真現像方式を用いた回路パターン形成方法であって、絶縁性のキャリア液と当該キャリア液に懸濁された帯電したトナー粒子とを含む現像液に、回路パターンの静電潜像が形成された感光体を浸漬し、当該静電潜像に前記トナー粒子を付着させて当該感光体上にトナー顕像を形成する現像工程と、前記トナー顕像を乾燥させて前記キャリア液を除去する乾燥工程と、乾燥させた前記トナー顕像を絶縁性基板に転写する転写工程と、転写された前記トナー顕像を加熱して回路パターンを焼成する焼成工程とを有することを特徴としている。しかし、感光体が必要になることや、トナー顕像を絶縁性基板に転写する転写工程が必要になることから、工程が煩雑になり、加工コストが高くなるという問題点がある。
特許文献４には、感光体を用いずに、絶縁基板に直接イオンフロー法で潜像を形成し、湿式現像法で着色トナーを付着させ、カラーフィルタを作製する方法が提案されている。しかし、イオンフロー法を用いる場合、任意の潜像パターンを形成するためには、多チャンネル化が必要であり、しかも、コロナ放電でイオンを発生させるために高電圧をかける必要がある。多チャンネルをＯＮ／ＯＦＦ制御する高電圧仕様の駆動回路が高価であることや、消費電力が大きいといった問題がある。また、イオンフロー装置の耐久性が低いことも問題になる。 The invention of Patent Document 3 is a circuit pattern forming method using a wet electrophotographic development system, in which a circuit containing an insulating carrier liquid and charged toner particles suspended in the carrier liquid is provided with a circuit. A developing step of immersing the photosensitive member on which the electrostatic latent image of the pattern is formed, attaching the toner particles to the electrostatic latent image to form a toner visible image on the photosensitive member, and drying the toner visible image A drying process for removing the carrier liquid, a transfer process for transferring the dried toner image onto an insulating substrate, and a baking process for heating the transferred toner image and baking the circuit pattern. It is characterized by having. However, since a photoconductor is required and a transfer process for transferring a toner visible image to an insulating substrate is required, there is a problem that the process becomes complicated and the processing cost increases.
Patent Document 4 proposes a method of forming a color filter by forming a latent image directly on an insulating substrate by an ion flow method without using a photoreceptor, and attaching a colored toner by a wet development method. However, when the ion flow method is used, in order to form an arbitrary latent image pattern, it is necessary to increase the number of channels, and it is necessary to apply a high voltage to generate ions by corona discharge. There is a problem that a high-voltage drive circuit for ON / OFF control of multiple channels is expensive and power consumption is large. Another problem is that the durability of the ion flow device is low.

次に、トナー担持体について説明する。トナー担持体は、電子写真式の画像形成装置に装備される現像装置を構成する要素であり、例えば現像ローラ等と称される。トナー担持体は現像剤を収容した現像容器に設けた開口部内に配置されてその外周面の一部を感光体と対向配置されている。感光体にトナー担持体を接触させない現像方式、いわゆる非接触現像方式がいくつか提案されており、クラウド法やジャンピング法による現像方式が知られている。このうち、クラウド法は、トナー担持体に２種類の電極を配置し、交番電圧を印加することにより、トナー担持体上のトナーをホッピングさせて感光体に現像する方式であり、非磁性一成分トナーを現像する方法として、優れた方式であることが知られている。
以下にその他の従来技術を記載する。
特許文献５には、現像剤担持搬送体を駆動させて現像剤を像担持体に搬送する現像装置において、上記現像剤担持搬送体によって搬送される現像剤を予備荷電する予備荷電手段を設けると共に、この現像剤担持搬送体上に電界カーテンを作用させる電界カーテン発生手段を設けたことを特徴とする現像装置が提案されている。
特許文献６には、粉体を静電力で移動させる静電搬送装置において、前記粉体を静電力で搬送、ホッピングさせるための電界を発生させる複数の電極を有する搬送基板を備え、前記電極の前記粉体進行方向における幅が前記粉体の平均粒径の１倍以上２０倍以下で、かつ、前記電極の前記粉体進行方向の間隔が前記粉体の平均粒径の１倍以上２０倍以下であり、各電極にはｎ相（ｎは３以上の整数）以上の駆動波形が印加されることを特徴とする静電搬送装置が提案されている。
上記搬送基板の電極は、蒸着法又は電着法で形成された後、エッチングでパターニングされたものであり、支持基板上にＡｌ、Ｎｉ−Ｃｒ等の導電性材料を０．１〜０．２μｍ厚で成膜し、これをフォトリソ技術等を用いて所要の電極形状にパターン化して形成している。これは、前述のフォトリソグラフィー法であり、フォトリソグラフィー法の問題点が生じることになる。 Next, the toner carrier will be described. The toner carrier is an element that constitutes a developing device provided in an electrophotographic image forming apparatus, and is called, for example, a developing roller. The toner carrier is disposed in an opening provided in a developer container containing a developer, and a part of the outer peripheral surface thereof is disposed to face the photoconductor. Several development methods that do not bring the toner carrier into contact with the photoreceptor, so-called non-contact development methods, have been proposed, and development methods using the cloud method or jumping method are known. Among these, the cloud method is a method in which two types of electrodes are arranged on a toner carrier and an alternating voltage is applied to hop toner on the toner carrier and develop it on a photosensitive member. It is known that this is an excellent method for developing toner.
Other conventional techniques are described below.
In Patent Document 5, in a developing device that drives a developer carrying transporter to transport the developer to an image carrier, a precharging unit that precharges the developer transported by the developer carrying transporter is provided. There has been proposed a developing device characterized in that an electric field curtain generating means for applying an electric field curtain is provided on the developer carrying carrier.
In Patent Document 6, an electrostatic transfer device that moves powder with electrostatic force includes a transfer substrate having a plurality of electrodes that generate an electric field for transferring and hopping the powder with electrostatic force. The width in the powder traveling direction is 1 to 20 times the average particle diameter of the powder, and the distance between the electrodes in the powder traveling direction is 1 to 20 times the average particle diameter of the powder. There has been proposed an electrostatic transfer device in which a drive waveform of n phase (n is an integer of 3 or more) or more is applied to each electrode.
The electrode of the transfer substrate is formed by vapor deposition or electrodeposition and then patterned by etching. A conductive material such as Al or Ni—Cr is 0.1 to 0.2 μm on the support substrate. The film is formed with a thickness, and this is formed by patterning into a required electrode shape using a photolithographic technique or the like. This is the above-described photolithography method, which causes a problem of the photolithography method.

特許文献７には、非磁性トナーを担持する現像剤担持体表面に、絶縁部を介して周期的な導電性電極パターンを設け、該電極に所望のバイアス電位を与えることで現像剤担持体表面近傍に電界勾配を発生せしめ、前記現像剤担持体上に前記非磁性トナーを付着搬送させることを特徴とする現像装置が提案されている。上記現像剤担持体の作製にあたっては、ポリイミドフィルム等の絶縁部材に電極を形成したものを通常の現像ローラの外周に貼り付けるという方法を採っており、これでは、ポリイミドフィルムを現像ローラの外周に貼り付けた時に生じるつなぎ目部の精度不良が画像品質の劣化を起こしてしまう。
特許文献８では、互いに絶縁された状態で所定方向に並ぶ複数の電極を有する電極パターンを備えた表面移動可能なトナー担持体を具備し、前記複数の電極中の所定の電極を起点にした奇数番目の電極の集合体である奇数番目電極群と偶数番目の電極の集合体である偶数番目電極群との間に電位差を生起せしめることで、前記トナー担持体の表面上のトナーを電極間で移動させながら前記トナー担持体の表面移動によって潜像担持体との対向位置まで搬送して前記潜像担持体上の潜像に付着させる現像装置において、奇数番目の電極と偶数番目の電極とにそれぞれ互いに位相ズレしたパルス電圧を印加することで前記トナー担持体の表面上のトナーを電極間で移動させるようにしたことを特徴とする現像装置を提案している。
上記トナー担持体は、絶縁体であるアクリル樹脂の円筒に軸穴を設け、ステンレス製の電極軸を円筒の軸穴に圧入して電極軸を奇数番目電極群、偶数番目電極群にそれぞれ接続する。次いで、トナー担持体の表面を外周旋削によって平滑に仕上げ、溝のピッチが１００［μｍ］、溝幅が５０［μｍ］となるように溝の切削を行う。溝切削を行ったローラに無電解ニッケルのメッキを施し、無電解ニッケルのメッキを施したローラの外周を旋削して不要な導体膜を取り除く。その後、ローラにシリコーン系樹脂をコーティングすることでローラの表面を平滑にし、同時に表面保護層（厚み約５［μｍ］、体積抵抗率約１０１０［Ω・ｃｍ］）を形成してトナー担持体を製作している。しかし、この方法では、製作工程が多く煩雑であり、溝加工を切削で行っているため加工時間が長く、加工コストが高くなるという問題点がある。

A developing device has been proposed in which an electric field gradient is generated in the vicinity so that the non-magnetic toner is adhered and conveyed on the developer carrying member. In producing the developer carrier, an insulating member such as a polyimide film having an electrode formed thereon is attached to the outer periphery of a normal developing roller. With this, the polyimide film is attached to the outer periphery of the developing roller. Poor accuracy at the joints that occur when pasting causes degradation of image quality.
In Patent Document 8, an odd-numbered surface including a surface-movable toner carrier having an electrode pattern having a plurality of electrodes arranged in a predetermined direction in a state of being insulated from each other, and starting from a predetermined electrode among the plurality of electrodes By causing a potential difference between the odd-numbered electrode group that is the aggregate of the second electrode and the even-numbered electrode group that is the aggregate of the even-numbered electrodes, the toner on the surface of the toner carrier is transferred between the electrodes. In the developing device for transporting to the position facing the latent image carrier by moving the surface of the toner carrier while being moved and attaching it to the latent image on the latent image carrier, the odd-numbered electrodes and even-numbered electrodes A developing device is proposed in which the toner on the surface of the toner carrying member is moved between the electrodes by applying pulse voltages that are out of phase with each other.
The toner carrier is provided with a shaft hole in an acrylic resin cylinder as an insulator, and a stainless steel electrode shaft is press-fitted into the cylindrical shaft hole to connect the electrode shaft to the odd-numbered electrode group and even-numbered electrode group, respectively. . Next, the surface of the toner carrier is smoothly finished by peripheral turning, and the grooves are cut so that the groove pitch is 100 [μm] and the groove width is 50 [μm]. Electroless nickel plating is applied to the groove-cut roller, and the outer periphery of the electroless nickel-plated roller is turned to remove unnecessary conductor films. Thereafter, the surface of the roller is smoothed by coating the roller with a silicone resin, and at the same time, a surface protective layer (thickness: about 5 [μm], volume resistivity: about 1010 [Ω · cm]) is formed to form a toner carrier. I'm making it. However, this method has many manufacturing steps and is complicated, and has a problem that the processing time is long and the processing cost is high because the grooving is performed by cutting.

A flat plate made of SUS was used as the conductive substrate 4, and a material obtained by adding a curing initiator to an uncured melamine resin was used as the insulating material 5. An uncured insulating material (insulating material layer) 5 was uniformly applied on the conductive substrate (SUS substrate) 4 so as to have a thickness of 20 μm, and was cured by heating at a temperature of 150 ° C. for 30 minutes.
In addition to SUS material, any material can be used for the conductive substrate 4, but aluminum, iron, copper, brass, etc. are used in consideration of material cost and processing cost. It is desirable to do.
The insulating material 5 is preferably a thermosetting resin, and in addition to melamine resin, epoxy resin, polyester resin, phenol resin, alkyd resin, polyurethane resin, silicon resin, polyimide resin, urea resin, aniline resin, furan resin, etc. Thermosetting resins and mixtures containing two or more of these thermosetting resins can also be used.

次に、図５は帯電部材に電位を与えて試料基板（基体）上に潜像イメージを形成させる方法を示す図であり、図５に基づいて配線パターン作製手順（帯電工程〜現像工程〜乾燥・加圧焼結工程）について説明する。
上記の工程で夫々製作された帯電部材６と試料基板７を図５に示すように１００ｍｍのギャップＧを隔てた非接触状態で対向してセットし、この状態で１ｋＶの電位を帯電部材６に与え、試料基板７の絶縁材料５上に潜像イメージを形成させた。
なお、電位の符号は正負いずれでもよく、現像工程で付着させる機能性微粒子の帯電性能で決まるものである。また、予め逆符号の電位で試料基板（基体）７全面を帯電させておき、帯電部材６で電位を与えてもよい。 Next, FIG. 5 is a diagram showing a method for forming a latent image on a sample substrate (substrate) by applying a potential to the charging member. A wiring pattern manufacturing procedure (charging process, developing process, drying) based on FIG. -Pressure sintering process) is demonstrated.
The charging member 6 and the sample substrate 7 respectively manufactured in the above steps are set to face each other in a non-contact state with a gap G of 100 mm as shown in FIG. 5, and in this state, a potential of 1 kV is applied to the charging member 6. Then, a latent image was formed on the insulating material 5 of the sample substrate 7.
The sign of the potential may be positive or negative, and is determined by the charging performance of the functional fine particles to be attached in the development process. Alternatively, the entire surface of the sample substrate (base body) 7 may be charged in advance with a reverse sign potential, and the potential may be applied by the charging member 6.

次いで、機能性微粒子を炭化水素溶媒（EXON ISOPAR-H）に分散させ、湿式現像法を用いて試料基板７上の絶縁材料５に形成された潜像に機能性微粒子を選択的に付着させた。ここで、機能性微粒子は、銀ナノ粒子を高分子材料でコートし、体積固有抵抗値が１０４Ｗ／ｃｍ³程度で、粒子径が１μｍ程度に調整された導電性微粒子を使用した。
次いで、試料基板７上の導電性微粒子を予備乾燥し、１５０℃のオーブンに入れて３０分間加圧焼成を行い、銀ナノ粒子を焼結させた。
この結果、パターンの形成は良好であり、得られた導電性微粒子のパターンの体積固有抵抗値が１０４Ｗ／ｃｍ³程度になることが確認された。
機能性微粒子を付着させる方法として、湿式現像法の他に乾式現像法でも良く、この方法は炭化水素溶媒を使用しないため湿式現像法よりも簡便な方法である。但し、乾式現像法に使用できる機能性微粒子は最小で４μｍ程度であるため、湿式現像法と比較して精細さに劣るといった欠点があるが、数十μｍ以上のパターン形成を目的とした場合には有意差が生じるものではない。 Next, the functional fine particles were dispersed in a hydrocarbon solvent (EXON ISOPAR-H), and the functional fine particles were selectively attached to the latent image formed on the insulating material 5 on the sample substrate 7 using a wet development method. . Here, as the functional fine particles, conductive fine particles in which silver nanoparticles were coated with a polymer material, a volume resistivity value of about 104 W / cm ³ and a particle diameter of about 1 μm were used.
Next, the conductive fine particles on the sample substrate 7 were pre-dried, put in an oven at 150 ° C., and baked under pressure for 30 minutes to sinter the silver nanoparticles.
As a result, it was confirmed that the pattern was satisfactorily formed, and the volume resistivity value of the obtained conductive fine particle pattern was about 104 W / cm ³ .
As a method for attaching the functional fine particles, a dry development method may be used in addition to the wet development method, and this method is simpler than the wet development method because a hydrocarbon solvent is not used. However, since the functional fine particles that can be used in the dry development method are about 4 μm at a minimum, there is a disadvantage that the fineness is inferior to that of the wet development method. Does not cause a significant difference.

Next, 20 mm of a negative photoresist (microchem SU-8) serving as the insulating material 8 is applied on the charging material 9, mask-exposed to selectively cure the photoresist, and an unexposed portion (unexposed) by development processing. The photoresist of the hardened portion) was removed to obtain a photoresist pattern, that is, a pattern 8a of the insulating material 8 (see a plan view of FIG. 6B).

以上のように本発明の各実施形態によれば以下のような効果を奏する。
まず、本発明は、基材、及び該基材面に形成され且つ形成しようとする静電パターンとほぼ同一のパターン形状を備えた導電材料を有した帯電部材を用意する工程と、導電性基板、及び該導電性基板面の少なくとも一部に形成された絶縁材料層を有した基体を用意する工程と、前記基体の絶縁材料層に前記帯電部材を用いて静電パターンを形成する工程と、導電性を有する粉体を前記静電パターン上に付着せしめて配線パターンを形成する工程と、を備えている。
このため、数μｍ〜数十μｍ幅の微細な電極パターンを精度良く、大量生産に向いた、生産効率の優れた方法で基体に形成することができ、非磁性一成分トナーの非接触現像を可能にするためのトナー担持体を提供することができる。
また、基体が、ローラ形状の部材であり、ローラ外周面上に絶縁材料層を設けて配線パターンを形成するので、加工装置の小型化が図れる。 As described above, according to each embodiment of the present invention, the following effects can be obtained.
First, the present invention provides a process for preparing a base member, and a charging member having a conductive material having a pattern shape substantially the same as the electrostatic pattern to be formed on the base surface, and a conductive substrate. And a step of preparing a base having an insulating material layer formed on at least a part of the surface of the conductive substrate; a step of forming an electrostatic pattern on the insulating material layer of the base using the charging member; And a step of depositing conductive powder on the electrostatic pattern to form a wiring pattern.
For this reason, it is possible to form a fine electrode pattern with a width of several μm to several tens of μm on a substrate with high accuracy, suitable for mass production, and with excellent production efficiency, and non-contact development of non-magnetic one-component toner. A toner carrier can be provided.
Further, since the base body is a roller-shaped member and an insulating material layer is provided on the outer peripheral surface of the roller to form a wiring pattern, the processing apparatus can be miniaturized.

また、帯電部材の基材上に製膜された導電材料層の上に、絶縁材料からなるパターン形状が形成されているので、パターン形状を有する絶縁材料で導電材料をマスクするだけの簡便な方法で、導電材料のパターン形状を得ることができ、帯電部材に電圧を印加することで、絶縁基体上に導電材料のパターン形状と同一の静電パターンを形成（複製）することが可能になる。
また、帯電部材の導電性の基材上に導電材料の有無から成る配線パターンが形成されているので、絶縁材料上に導電材料のパターンを形成するだけの簡便な方法で、導電材料のパターン形状を得ることができ、帯電部材に電圧を印加することで、絶縁基体上に導電材料のパターン形状と同一の静電パターンを形成（複製）することが可能になる。
また、帯電部材が平板形状であるので、導電材料のパターンを形成することが簡単になり、パターンの形状精度も高いものが得られる。 Also, since the pattern shape made of the insulating material is formed on the conductive material layer formed on the base member of the charging member, a simple method of simply masking the conductive material with the insulating material having the pattern shape Thus, a pattern shape of the conductive material can be obtained, and by applying a voltage to the charging member, an electrostatic pattern identical to the pattern shape of the conductive material can be formed (replicated) on the insulating substrate.
In addition, since a wiring pattern consisting of the presence or absence of a conductive material is formed on the conductive base material of the charging member, the pattern shape of the conductive material can be obtained simply by forming a conductive material pattern on the insulating material. By applying a voltage to the charging member, it is possible to form (reproduce) an electrostatic pattern identical to the pattern shape of the conductive material on the insulating substrate.
Further, since the charging member has a flat plate shape, it is easy to form a pattern of the conductive material, and a pattern having high shape accuracy can be obtained.

また、帯電部材がベルト形状であるので、連続的な静電パターンを形成する場合や、大面積化に対応しやすくなる。また、ベルト形状はフレキシブルに対応できるため、装置構成の自由度が大きくなる。
また、帯電部材が、ローラ形状であるため、連続的な静電パターンを形成する場合や、大面積化に対応しやすくなる。また、瞬間的な帯電領域が微小範囲になるため、帯電が安定し、精度の高い静電パターンを得ることができる。
また、ローラ形状の前記帯電部材の外径と、ローラ形状の前記基体の外径がほぼ同径であり、静電パターン形成時に前記帯電部材と前記基体をそれぞれ回転させ、その角速度を同じにするため、つなぎ目部（ローラ形状における潜像形成の始点と終点）の静電パターンの形状精度を高くすることができ、画像劣化の少ないトナー担持体を得ることができる。
また、帯電部材を、基体の一部に設けた絶縁材料層に接触させた状態で電位差を与えることで、導電材料で形成されたパターン形状とほぼ同一の静電パターンを前記絶縁層に形成するので、帯電部材と基体の位置関係（帯電ギャップ）を一定にすることができ、帯電量が安定した静電イメージを形成することができる。その結果、導電性トナーの付着量も安定し、配線抵抗のばらつきが少なく、トナー担持体の性能も向上する。 Further, since the charging member has a belt shape, it is easy to cope with a case where a continuous electrostatic pattern is formed or an increase in area. Further, since the belt shape can be flexibly adapted, the degree of freedom of the device configuration is increased.
Further, since the charging member has a roller shape, it is easy to cope with a case where a continuous electrostatic pattern is formed or an increase in area. In addition, since the instantaneous charging region is in a very small range, charging is stable and a highly accurate electrostatic pattern can be obtained.
Also, the outer diameter of the roller-shaped charging member and the outer diameter of the roller-shaped base are approximately the same, and the electrostatic member is rotated to make the angular velocity the same when forming the electrostatic pattern. Therefore, the shape accuracy of the electrostatic pattern at the joint portion (starting point and end point of latent image formation in the roller shape) can be increased, and a toner carrier with little image deterioration can be obtained.
Further, by applying a potential difference in a state where the charging member is in contact with the insulating material layer provided on a part of the base, an electrostatic pattern substantially the same as the pattern shape formed of the conductive material is formed on the insulating layer. Therefore, the positional relationship (charging gap) between the charging member and the substrate can be made constant, and an electrostatic image with a stable charge amount can be formed. As a result, the adhesion amount of the conductive toner is stabilized, there is little variation in wiring resistance, and the performance of the toner carrier is improved.

また、帯電部材を、基体の一部に設けた絶縁材料層と微少な空隙を設けて配置した状態で電位差を与えることで、導電材料形成されたパターン形状とほぼ同一の静電パターンを前記絶縁層に形成するので、帯電領域を拡大して、加工速度を上げることが可能になる。
また、基体の一部に設けた絶縁層を、予め正負いずれか一方の電荷で帯電させた後、前記帯電部材によって、逆符号の電荷のパターンを形成するので、基体上に形成されたトナーと同符号の電荷がトナーと反発するために、地汚れ（不要な箇所にトナーが付着すること）の少ない配線パターンが得られ、ショート（短絡）することのない部品信頼性の高いトナー担持体を得ることができる。
また、導電性を有する粉体を静電パターン上に付着せしめる方法として、乾式現像法を用いるので、湿式現像法（液体現像法）と比較して、溶剤レスで安全性が高く、環境負荷の少ない方法であり、加工装置のコストも安くなる。
また、導電性を有する粉体を静電パターン上に付着せしめる方法として、湿式現像法（液体現像法）を用いるので、使用するトナー粒径が乾式現像法より小さくなるため、配線パターン（電極幅、ピッチ）を微細化することができる。 In addition, by applying a potential difference in a state where the charging member is disposed with a small gap provided between the insulating material layer provided on a part of the base, the electrostatic pattern substantially the same as the pattern shape formed with the conductive material is insulated. Since it forms in a layer, it becomes possible to enlarge a charged area and to raise a processing speed.
In addition, after the insulating layer provided on a part of the base is charged with either positive or negative charge in advance, the charging member forms a pattern with a reverse sign, so that the toner formed on the base and Since the charge of the same sign is repelled from the toner, a wiring pattern with less background contamination (toner adheres to unnecessary parts) can be obtained, and a highly reliable toner carrier that does not short-circuit Obtainable.
In addition, as a method for depositing conductive powder on the electrostatic pattern, a dry development method is used. Therefore, compared to a wet development method (liquid development method), it is safer and has a higher safety, and has an environmental impact. There are few methods, and the cost of the processing apparatus is also reduced.
In addition, since the wet development method (liquid development method) is used as a method for depositing conductive powder on the electrostatic pattern, the toner particle size used is smaller than that of the dry development method. , Pitch) can be miniaturized.

また、トナー担持体において、上記いずれかの方法により、基体の一部に設けた絶縁層上に配線パターンが形成されるので、地汚れの発生を抑えることができるホッピング方式の画像形成装置を提供することができる。
