Description
本発明は、電子写真装置（コピー、プリンタ、ファクシミリ）に設置される接触帯電ブラシ、クリーニングブラシ、除電ブラシに適する導電性複合繊維に関するものである。 The present invention relates to a conductive composite fiber suitable for a contact charging brush, a cleaning brush, and a static elimination brush installed in an electrophotographic apparatus (copy, printer, facsimile).
一般に電子写真装置（コピー、プリンタ、ファクシミリ）では、光導電性の感光体表面を一様に帯電し、露光によって静電潜像を形成し、この静電潜像にトナーを静電的に付着させて現像し、得られたトナー像を記録用紙に転写、定着させて像を可視化させる。転写後は感光体上に未転写のトナーが残存しているため、クリーニング装置により、清掃、除去を行う。これらの操作を繰り返し行い、連続的に画像を形成している。 In general, in an electrophotographic apparatus (copy, printer, facsimile), the surface of a photoconductive photosensitive member is uniformly charged, an electrostatic latent image is formed by exposure, and toner is electrostatically attached to the electrostatic latent image. The developed toner image is transferred and fixed on a recording sheet to visualize the image. After transfer, untransferred toner remains on the photoreceptor, and cleaning and removal are performed by a cleaning device. These operations are repeated to continuously form images.
従来、感光体などの被帯電体を帯電させる装置として、コロナ帯電装置及び接触帯電装置が採用されている。コロナ放電装置は金属ワイヤーとシールド電極からなっているが、高価な数千ボルト（５ｋＶ〜８ｋＶ程度）の高電圧電源を必要とし、また、コロナ放電時に人体に有害なオゾンが発生するなどの問題点がある。それらのことから、最近では導電性ゴムローラーや導電性繊維を植毛したブラシ或いは導電性のブレードなどの導電体に比較的低電圧（１ｋＶ〜２ｋＶ程度）を印可し、該導電体を感光体に接触させて直接帯電させる接触帯電方式の帯電装置が提案され、実用化されるようになってきた。接触帯電ブラシは米国特許第４３７１２５２号明細書及び特開平６−２７４００９号公報には、導電性繊維からなる帯電ブラシが開示されている。 Conventionally, a corona charging device and a contact charging device have been adopted as devices for charging a charged body such as a photoconductor. The corona discharge device consists of a metal wire and a shield electrode, but it requires an expensive high-voltage power supply of several thousand volts (about 5 kV to 8 kV), and ozone is harmful to the human body during corona discharge. There is a point. Therefore, recently, a relatively low voltage (about 1 kV to 2 kV) is applied to a conductive material such as a conductive rubber roller, a brush in which conductive fibers are implanted, or a conductive blade, and the conductive material is used as a photosensitive material. Contact charging type charging devices that are directly charged by contact have been proposed and put into practical use. As for the contact charging brush, US Pat. No. 4,371,252 and JP-A-6-274209 disclose charging brushes made of conductive fibers.
コロナ放電装置と比べて、印加電圧が低電圧で済むことが特徴である接触帯電方式であるが、従来の帯電ブラシの場合、使用される導電性繊維の繊維径の大きさから感光体表面を均一に帯電させることができず、帯電ブラシ使用の画像形成装置で得られる画像の画質はムラ等が生じる場合がある。 Compared to corona discharge devices, this is a contact charging method characterized by a low applied voltage. In the case of conventional charging brushes, the surface of the photoconductor is determined by the size of the diameter of the conductive fibers used. The image cannot be uniformly charged, and the image quality obtained by the image forming apparatus using the charging brush may be uneven.
従って、本発明の目的は、被帯電体を均一に帯電することができる帯電ブラシ及び帯電ブラシを構成する機械的物性に優れた導電性複合繊維を提供することにある。 Accordingly, an object of the present invention is to provide a charging brush capable of uniformly charging an object to be charged and a conductive conjugate fiber having excellent mechanical properties constituting the charging brush.
更に詳しく、本発明の課題を見る。電子写真装置の感光体を帯電させるための帯電ブラシはある一定の導電性を持つ導電性繊維で構成されることは必要不可欠である。さらに良好な画像を得るためには感光体表面を均一に帯電させることが必要で、均一に帯電させるためには、一般に、より繊度の低い導電性繊維が求められている。しかしながら、感光体を十分に帯電させることのできる導電性を持つ程度の導電性粒子の含有率を有する導電性繊維及び導電性複合繊維の繊度を低くすることは繊維形成の紡糸工程、延撚工程において困難であり、改善が求められてきた。さらに、導電層のみで形成される繊維は強度、伸度が低く、さらに繊度を低くすると、ブラシ化する際のパイル織が困難であること、また、ブラシにした場合に毛倒れ、あるいはへたりが生じ、ブラシとしての耐久性に問題が生じる。 In more detail, the subject of the present invention is seen. It is indispensable that the charging brush for charging the photoreceptor of the electrophotographic apparatus is composed of conductive fibers having a certain conductivity. In order to obtain a better image, it is necessary to uniformly charge the surface of the photoreceptor, and in order to uniformly charge, generally a conductive fiber having a lower fineness is required. However, reducing the fineness of the conductive fiber and conductive composite fiber having a conductive particle content sufficient to sufficiently charge the photosensitive member is a fiber forming spinning process and a twisting process. However, improvement has been demanded. Furthermore, the fiber formed only by the conductive layer has low strength and elongation, and if the fineness is further reduced, pile weaving when making a brush is difficult, and when it is made into a brush, it falls down or sags. This causes a problem in durability as a brush.
したがって、本発明の課題は、電子写真装置の感光体を帯電させる帯電ブラシに使用される導電性繊維において、より良好な画質を得るために、感光体をより均一に帯電させることのできる帯電ブラシに使用されるような導電性複合繊維の発明にある。 Accordingly, an object of the present invention is to provide a charging brush capable of charging a photoconductor more uniformly in order to obtain better image quality in a conductive fiber used for a charging brush for charging a photoconductor of an electrophotographic apparatus. In the invention of the conductive composite fiber as used in the present invention.
即ち、本発明は、被帯電体に接触配置され、電圧を印加することにより該被帯電体に接触するブラシ接触子に用いられる導電性複合繊維であって、該複合繊維が導電性粒子を含有する熱可塑性重合体からなる導電層と該導電層の熱可塑性重合体と相溶性のある熱可塑性重合体からなる非導電層が接合されてなり、導電層が連続した非導電層により複数の領域に分離され、各導電層の繊度が１．５ｄｔｅｘ以下となるようにし、かつ全ての導電層の少なくとも一部が繊維表面に露出するように配されることを特徴とする導電性複合繊維及びその繊維からなる電子写真装置の接触帯電ブラシである。 That is, the present invention is a conductive conjugate fiber used for a brush contact that is placed in contact with a member to be charged and contacts the member to be charged by applying a voltage, and the conjugate fiber contains conductive particles. A conductive layer made of a thermoplastic polymer and a non-conductive layer made of a thermoplastic polymer compatible with the thermoplastic polymer of the conductive layer are joined together, and the conductive layer is formed into a plurality of regions by a continuous non-conductive layer. A conductive composite fiber, wherein the conductive layers are arranged so that each conductive layer has a fineness of 1.5 dtex or less and at least a part of all the conductive layers are exposed on the fiber surface, and It is a contact charging brush of an electrophotographic apparatus made of fiber.
本発明により、繊維形成、ブラシ化におけるパイル織も容易で、かつ、電子写真装置の帯電ブラシとして使用した際にへたり等もなく、感光体表面を均一に帯電させることができ、良好な画質を得ることが可能となる。 According to the present invention, pile weaving in fiber formation and brushing is easy, and there is no sag when used as a charging brush for an electrophotographic apparatus, and the surface of the photoconductor can be uniformly charged, resulting in good image quality. Can be obtained.
本発明の導電性複合繊維の導電層に使用される導電性粒子としては、カーボンブラック、導電性酸化チタンが知られている。カーボンブラックにはファーネスブラック、アセチレンブラック、ケッチェンブラックなどが知られているが、繊維形成時の帯電ブラシ用途での導電性能を満たすならばこれに限らない。導電性皮膜を有する酸化チタンの導電性皮膜には酸化錫をドーピングしたアンチモンが知られている。 Carbon black and conductive titanium oxide are known as conductive particles used in the conductive layer of the conductive composite fiber of the present invention. As carbon black, furnace black, acetylene black, ketjen black, and the like are known. Antimony doped with tin oxide is known as a conductive film of titanium oxide having a conductive film.
導電性粒子を含有する導電層に使用される熱可塑性重合体と非導電層を構成する熱可塑性重合体は相溶性があることが必要である。導電層と非導電層の組み合わせの一例として、導電層、非導電層を形成する重合体がともにポリアミド、もしくは、導電層、非導電層を形成する重合体がともにポリエステルとなる組み合わせがあるが、両ポリマーが相溶性であればこれに限らない。導電層がポリアミド、非導電層がポリエステルでは相溶性がなく、繊維を延伸する際、または、繊維に物理的な負荷をかけた際に導電層が脱落し、感光体を均一に帯電させる機能が低下する。 The thermoplastic polymer used in the conductive layer containing conductive particles and the thermoplastic polymer constituting the non-conductive layer must be compatible. As an example of the combination of the conductive layer and the nonconductive layer, there is a combination in which the polymer forming the conductive layer and the nonconductive layer is both polyamide, or the polymer forming the conductive layer and the nonconductive layer is both polyester. If both polymers are compatible, it will not be restricted to this. When the conductive layer is polyamide and the non-conductive layer is polyester, they are not compatible, and when the fiber is stretched or when a physical load is applied to the fiber, the conductive layer falls off, and the photoreceptor is charged uniformly. descend.
導電層、非導電層に使用されるポリアミドは、ナイロン６、ナイロン６６、ナイロン１１、ナイロン１２及びこれらを主成分とする共重合体が知られているが、これらだけでなく、繊維形成能を持つポリアミドであればよい。導電層、非導電層に使用されるポリエステルは、ポリエチレンテレフタレート、ポリブチレンテレフタレート、ポリエチレンナフタレート及びこれらを主成分とする共重合体が知られているが、これらだけでなく、繊維形成能を持つポリエステルであればよい。 As the polyamide used for the conductive layer and the non-conductive layer, nylon 6, nylon 66, nylon 11, nylon 12 and copolymers based on these are known, but not only these but also fiber forming ability. Any polyamide may be used. Polyesters used for the conductive layer and the non-conductive layer are known as polyethylene terephthalate, polybutylene terephthalate, polyethylene naphthalate and copolymers based on these, but also have fiber-forming ability. Any polyester may be used.
導電性粒子の重量含有率は、帯電ブラシの要求性能により、１０ｗｔ％〜８０ｗｔ％であることが必要であり、１５〜７０％であればより好ましい。１０ｗｔ％未満であると導電性が発現しにくく、８０ｗｔ％であると、繊維形成が困難となる。例えば、導電性粒子が３０ｗｔ％前後含有した導電層部を繊維質量に対し３０ｗｔ％〜６０ｗｔ％配することで、比抵抗が１×１０５Ω・ｃｍ程度の導電性を示す導電性繊維を得ることができる。 The weight content of the conductive particles needs to be 10 wt% to 80 wt%, more preferably 15 to 70%, depending on the required performance of the charging brush. If it is less than 10 wt%, the conductivity is hardly expressed, and if it is 80 wt%, fiber formation becomes difficult. For example, conductive fibers having a specific resistance of about 1 × 10 5 Ω · cm can be obtained by arranging conductive layer portions containing about 30 wt% of conductive particles in an amount of 30 wt% to 60 wt% with respect to the fiber mass. be able to.
本発明の導電性複合繊維は図１から図３に示した代表例のように、導電性粒子を含有した導電層が非導電層によって複数の領域に分離し、かつ、各導電層の一部が繊維表面に露出し、さらには、導電層：非導電層の断面積比が３：２〜１０：１で、該導電性複合繊維の単糸繊度が７．５ｄｔｅｘ以下、導電層の繊度が１．５ｄｔｅｘ以下となる繊維断面を
持つ。
In the conductive conjugate fiber of the present invention, as in the representative examples shown in FIGS. 1 to 3, the conductive layer containing conductive particles is separated into a plurality of regions by the non-conductive layer, and a part of each conductive layer Is exposed to the fiber surface, and the cross-sectional area ratio of the conductive layer: non-conductive layer is 3: 2 to 10: 1, the single yarn fineness of the conductive conjugate fiber is 7.5 dtex or less, and the fineness of the conductive layer is It has a fiber cross section of 1.5 dtex or less.
導電性粒子を含有した導電層が繊維断面において非導電層によって複数の領域に分離され、各導電層の繊度が１．５ｄｔｅｘ以下となることが必要であり、０．１ｄｔｅｘ〜１．０ｄｔｅｘであるとより好ましい。各導電層の繊度が１．５ｄｔｅｘを超えると感光体を均一に帯電させることができない。 The conductive layer containing the conductive particles is separated into a plurality of regions by the non-conductive layer in the fiber cross section, and the fineness of each conductive layer is required to be 1.5 dtex or less, and is 0.1 dtex to 1.0 dtex. And more preferred. If the fineness of each conductive layer exceeds 1.5 dtex, the photoreceptor cannot be charged uniformly.
導電層：非導電層の断面積比は３：２〜１０：１であることが必要であり、２：１〜８：１であるとより好ましい。導電層：非導電層の断面積比が３：２よりも非導電層が大きくなると、感光体に接触する導電層が少なくなり、感光体を均一に帯電することができない。導電層：非導電層の断面積比が１０：１よりも導電層が大きくなると、繊維形成が困難となる。 The cross-sectional area ratio of the conductive layer: non-conductive layer needs to be 3: 2 to 10: 1, and more preferably 2: 1 to 8: 1. If the cross-sectional area ratio of the conductive layer: non-conductive layer is larger than 3: 2, the conductive layer in contact with the photoconductor is reduced and the photoconductor cannot be uniformly charged. If the conductive layer: non-conductive layer cross-sectional area ratio is larger than 10: 1, fiber formation becomes difficult.
各導電層の一部が繊維表面に露出していることが必要である。導電層が露出していないと、ブラシの繊維先端が感光体に斜めから接触するために、導電層が感光体に接触することが難しくなり、感光体を十分に帯電させることができない。 It is necessary that a part of each conductive layer is exposed on the fiber surface. If the conductive layer is not exposed, the fiber tip of the brush comes into contact with the photoreceptor at an angle, so that it becomes difficult for the conductive layer to contact the photoreceptor, and the photoreceptor cannot be charged sufficiently.
導電層の比抵抗は帯電ブラシの要求性能により、１×１０１Ω・ｃｍ〜１×１０１２Ω・ｃｍであることが望ましく、この範囲であれば、この導電性繊維を用いて作製されたブラシを帯電ブラシとして用いた場合、良好な画質を得ることができる。 The specific resistance of the conductive layer is preferably 1 × 10 1 Ω · cm to 1 × 10 12 Ω · cm, depending on the required performance of the charging brush. When the brush is used as a charging brush, good image quality can be obtained.
該導電性複合繊維の導電層に使用される樹脂と導電性粒子の混合は二軸混練機などの公知の方法にて混練することができる。得られた導電性樹脂と非導電層に使用される樹脂をそれぞれ溶融し、例えば図１に示す断面形状になるような紡糸口金より吐出する。吐出した導電性複合繊維を冷風にて冷却後、適当な油剤を付与し、公知の巻き取り機にて巻き取り、マルチフィラメントの未延伸糸を得る。巻き取り速度は導電層、非導電層の組み合わせ、比率等により適正なスピードであれば良いが、繊維物性、巻き取り易さ等により、６００ｍ／ｍｉｎ〜１２００ｍ／ｍｉｎが望ましい。得られた未延伸糸を７０℃〜１２０℃の熱をかけながら延伸して、延伸糸を得る。延伸後の繊維全繊度は後の織機の能力、糸密度にもよるが、５０ｄｔｅｘ〜５００ｄｔｅｘが望ましい。得られた導電性複合繊維をパイル織等で例えば１２．４ｋｆ／ｃｍ２〜３１．０ｋｆ／ｃｍ２の帯電ブラシ容基布とし、該基布の裏面に導電性のバックコート剤を塗布し、金属の芯材に両面テープ等で貼り付けブラシを得る。ブラシ状にした後、起毛処理、シャーリング処理を行い、帯電ブラシを得る。 The resin used for the conductive layer of the conductive conjugate fiber and the conductive particles can be mixed by a known method such as a biaxial kneader. The obtained conductive resin and the resin used for the non-conductive layer are respectively melted and discharged from a spinneret having a cross-sectional shape shown in FIG. After cooling the discharged conductive conjugate fiber with cold air, an appropriate oil agent is applied, and it is wound up by a known winder to obtain a multifilament undrawn yarn. The winding speed may be an appropriate speed depending on the combination and ratio of the conductive layer and the non-conductive layer, but is preferably 600 m / min to 1200 m / min depending on the fiber properties and the ease of winding. The obtained undrawn yarn is drawn while applying heat at 70 ° C. to 120 ° C. to obtain a drawn yarn. The total fineness of the fiber after drawing depends on the ability of the subsequent loom and the yarn density, but is preferably 50 dtex to 500 dtex. The obtained conductive conjugate fiber is made into, for example, a 12.4 kf / cm 2 to 31.0 kf / cm 2 charged brush base fabric with pile weave, and a conductive back coat agent is applied to the back surface of the base fabric, A brush is affixed to a metal core with double-sided tape or the like. After making into a brush shape, brushing and shearing are performed to obtain a charged brush.
以上のように構成される導電性複合繊維は、電子写真装置の感光体表面を均一に帯電させることが可能で、かつ、繊維形成、ブラシ化のパイル織も容易となり、帯電ブラシとして適する。また、本ブラシは感光体のクリーニングブラシ及び中間転写ブラシ等の電子写真装置に用いられるあらゆるブラシに使用することができる。 The conductive conjugate fiber configured as described above can uniformly charge the surface of the photoreceptor of the electrophotographic apparatus, and can be easily formed into a fiber and formed into a pile, and is suitable as a charging brush. Further, this brush can be used for all brushes used in electrophotographic apparatuses such as a photoconductor cleaning brush and an intermediate transfer brush.
次に、実施例において、本発明の詳細を説明する。なお、実施例における比抵抗は導電性繊維全フィラメントを１１ｃｍ採取してその両端０．５ｃｍに導電性ペーストを塗布しアルミ箔に接着させ、アルミ箔を電極として測定した電気抵抗値より換算した。 Next, details of the present invention will be described in Examples. In addition, the specific resistance in an Example was converted from the electrical resistance value which measured 11cm of conductive fiber all filaments, apply | coated the conductive paste to the both ends 0.5cm, and was made to adhere to aluminum foil, and measured aluminum foil as an electrode.
電気抵抗測定機は、ヒューレットパッカード社製ハイレジスタンスメーター４３３９Ｂを使用した。 A high resistance meter 4339B manufactured by Hewlett-Packard Company was used as the electrical resistance measuring machine.
また、紡糸性の評価は未延伸糸採取時の１ボビンの巻き取り時間を１時間とし、１０ボビン巻き取りのうち何ボビン糸切れを起こすか（ボビン率）で判断し、ボビン率が８０％
以上であれば紡糸性良好とした。
The evaluation of the spinnability is based on the bobbin winding time of 1 bob when collecting undrawn yarn, and judging by how many bobbin yarn breaks out of 10 bobbin windings (bobbin rate). The bobbin rate is 80%.
If it was above, it was set as the spinning property favorable.
ブラシ作製時の毛倒れ、へたりについては目視にて評価した。毛倒れ、へたりがなければ○、あれば×とした。 The hair collapse and sag during brush production were evaluated visually. If there was no hair fall and sag, it was rated as ○, and if it was not, it was rated as ×.

Therefore, a test image is printed by incorporating the brushes produced by the methods of the following examples and comparative examples into an electrophotographic apparatus. And visually evaluated. The evaluation result was “good” if it was good, and “poor” if it was bad.
