Description
本発明は、複写機やプリンタ等の電子写真方式の画像形成装置に用いられる無端ベルトに関し、更に、像担持体に担持されたトナー画像を記録媒体に転写するとともに該トナー画像が転写された記録媒体を搬送する記録媒体搬送装置、像担持体に担持されたトナー画像を転写して保持するとともに保持されたトナー画像を記録媒体に転写する中間転写装置、及び画像形成装置に関するものである。 The present invention relates to an endless belt used in an electrophotographic image forming apparatus such as a copying machine or a printer, and further transfers a toner image carried on an image carrier to a recording medium and records the toner image transferred thereon. The present invention relates to a recording medium conveying apparatus that conveys a medium, an intermediate transfer apparatus that transfers and holds a toner image carried on an image carrier, and transfers a held toner image to a recording medium, and an image forming apparatus.
従来、電子写真方式の画像形成装置は、無機又は有機材料からなる像担持体上に一様な電荷を形成し、画像信号を変調したレーザー光等で前記像担持体上に静電潜像を形成した後に、帯電したトナーで前記静電潜像を現像してトナー像として可視化し、前記トナー像を直接記録紙等に搬送転写装置で転写するか、あるいは、中間転写装置を介して転写することにより所要の画像を得ている。 Conventionally, an electrophotographic image forming apparatus forms a uniform charge on an image carrier made of an inorganic or organic material, and forms an electrostatic latent image on the image carrier with a laser beam or the like that modulates an image signal. After the formation, the electrostatic latent image is developed with charged toner to be visualized as a toner image, and the toner image is directly transferred to a recording sheet or the like by a transfer transfer device or transferred via an intermediate transfer device. Thus, the required image is obtained.
前記搬送転写装置としては、転写ベルトを前記像担持体に接触させ、その接触部に記録紙等を挟持搬送することにより、記録紙上にトナー像を転写するものである（例えば、特許文献１参照。）。 The conveyance transfer device transfers a toner image onto a recording sheet by bringing a transfer belt into contact with the image carrier and sandwiching and conveying the recording sheet or the like to the contact portion (see, for example, Patent Document 1). .)
前記中間転写装置としては、像担持体上の未定着トナー像を中間転写ベルトに一次転写し、改めてこの未定着トナー像を前記中間転写ベルトから記録紙へ二次転写して記録紙上にトナー像を転写するものである（例えば、特許文献２参照。）。前記中間転写方式は、特にカラー画像形成装置では、中間転写ベルト上に多重転写された合成像を記録紙に一括転写するので、記録紙の厚みや表面特性等の要因に左右されずに、良好な画質が得られるといった利点がある。 As the intermediate transfer device, an unfixed toner image on an image carrier is primarily transferred to an intermediate transfer belt, and this unfixed toner image is secondarily transferred from the intermediate transfer belt to a recording sheet to newly transfer the toner image onto the recording sheet. (For example, refer to Patent Document 2). The intermediate transfer method is excellent in that it is not influenced by factors such as the thickness and surface characteristics of the recording paper because the composite image that has been multiple-transferred onto the intermediate transfer belt is collectively transferred onto the recording paper, particularly in a color image forming apparatus. There is an advantage that a good image quality can be obtained.
前記搬送転写装置又は前記中間転写装置の転写ベルト又は中間転写ベルトの表面汚れを除去するために、従来、転写ベルト又は中間転写ベルトにクリーニングブレードを当接させ、その表面をクリーンな状態に保つようにしていた。 In order to remove the surface contamination of the transfer belt or the intermediate transfer belt of the transport transfer device or the intermediate transfer device, conventionally, a cleaning blade is brought into contact with the transfer belt or the intermediate transfer belt so as to keep the surface clean. I was doing.
また、前記特許文献１には、像担持体と接触する転写体表面（転写ベルト）の十点平均粗さを３．５μｍ以下とすることで、確実なクリーニング性能を得られる旨が記載されている。 Further, Patent Document 1 describes that a reliable cleaning performance can be obtained by setting the 10-point average roughness of the transfer member surface (transfer belt) in contact with the image carrier to 3.5 μm or less. Yes.
また、前記特許文献２には、中間転写体の転写面を構成する材料の表面粗さが０．３５μｍ以下であり、潜像担持体と前記中間転写体との間のニップ圧力が０．８ｋｇ／ｃｍ２以下とすることで、中間転写体表面にトナーが埋没することを防止してベルト表面上に形成されたトナー像の記録媒体への転写（二次転写）を十分に行って、ライン画像の転写において線が欠ける等の画質欠陥が生じないようにするとともに、さらに未転写トナーが減少するため中間転写体の清掃部材の長寿命化を図ることができる旨が記載されている。 In Patent Document 2, the surface roughness of the material constituting the transfer surface of the intermediate transfer member is 0.35 μm or less, and the nip pressure between the latent image carrier and the intermediate transfer member is 0.8 kg. / Cm 2 or less, the toner is prevented from being buried on the surface of the intermediate transfer member, and the transfer of the toner image formed on the belt surface to the recording medium (secondary transfer) is sufficiently performed. It is described that it is possible to prevent the occurrence of image quality defects such as lack of lines in image transfer and to further extend the life of the cleaning member for the intermediate transfer member because untransferred toner is reduced.
しかしながら、上記従来の画像形成装置では、クリーニングブレードが転写ベルト又は中間転写ベルトの回転に巻き込まれて損傷するといった問題が生じていた。 However, the conventional image forming apparatus has a problem that the cleaning blade is damaged by being caught in the rotation of the transfer belt or the intermediate transfer belt.

However, the dimensions, materials, shapes, relative arrangements, and the like of the components described in this embodiment are not intended to limit the scope of the present invention only to those unless otherwise specified. Absent.
〔無端ベルト〕
図１は本発明の無端ベルトを示した図である。本発明の無端ベルトは、厚さ５０〜２００μｍ、体積固有抵抗１０８〜１０１２Ωｃｍ、転写面での表面抵抗率が１０９〜１０１４Ωｃｍ程度に調整された樹脂フィルムが用いられる。
[Endless belt]
FIG. 1 is a view showing an endless belt of the present invention. For the endless belt of the present invention, a resin film having a thickness of 50 to 200 μm, a volume specific resistance of 10 8 to 10 12 Ωcm, and a surface resistivity on the transfer surface of about 10 9 to 10 14 Ωcm is used.
無端ベルト構造としては、単層又は多層のいずれでもよい。前記無端ベルトの基材には、樹脂フィルムとしては任意の公知の熱可塑性樹脂から選ばれるが、好ましくは、ポリフッ化ビニリデン、フッ化ビニリデン共重合体、ポリエステル、ポリカーボネート、アクリル共重合体、ポリオレフィン、ＡＢＳが好ましい。これらのなかでも、２００〜２５０℃という低温で加工でき、難燃性に優れるという観点からポリフッ化ビニリデン、ポリカーボネートが好ましい。 The endless belt structure may be either a single layer or a multilayer. The base material of the endless belt is selected from any known thermoplastic resin as the resin film, preferably, polyvinylidene fluoride, vinylidene fluoride copolymer, polyester, polycarbonate, acrylic copolymer, polyolefin, ABS is preferred. Among these, polyvinylidene fluoride and polycarbonate are preferable from the viewpoint that they can be processed at a low temperature of 200 to 250 ° C. and are excellent in flame retardancy.
ベルト構造として多層構造の無端ベルトである場合には、前記基材樹脂の転写面にアクリル樹脂、フッ素樹脂、ポリエステル樹脂等の表面層（塗膜）が塗工等により形成される。 When the belt structure is an endless belt having a multilayer structure, a surface layer (coating film) such as an acrylic resin, a fluororesin, or a polyester resin is formed on the transfer surface of the base resin by coating or the like.
さらに、これらの前記基材及び表面層の各層には、導電性を付与するために導電性フィラーが添加される。導電性フィラーとしてはカーボンブラック、導電性酸化スズ等が選ばれる。 Further, a conductive filler is added to each of the base material and the surface layer in order to impart conductivity. Carbon black, conductive tin oxide and the like are selected as the conductive filler.
前記無端ベルトは、クリーニングブレードとの間で発生する摩擦抵抗を低減するため、無端ベルトの外周面に無端長手方向に連続あるいは断続して延びる溝が形成される。 In order to reduce the frictional resistance generated between the endless belt and the cleaning blade, a groove extending continuously or intermittently in the endless longitudinal direction is formed on the outer peripheral surface of the endless belt.
このような溝形状は、特に限定されるものではないが、最外周面に前記溝を形成した前記無端ベルト外周面の無端長手方向に直行する幅方向の表面粗さが１０点平均粗さで０．２〜０．６μｍとなるような溝であることが望ましい。 Such a groove shape is not particularly limited, but the surface roughness in the width direction perpendicular to the endless longitudinal direction of the endless belt outer peripheral surface in which the groove is formed on the outermost peripheral surface is an average roughness of 10 points. The groove is preferably 0.2 to 0.6 μm.
１０点平均粗さが０．２以下であると、クリーニングブレードと前記無端ベルトとの間に生じる摩擦抵抗を十分に低減することが出来ない。また、１０点平均粗さが０．６以上であると、前記クリーニングブレードによる前記無端ベルト表面の確実なクリーニング性能を得ることが困難となる。 When the 10-point average roughness is 0.2 or less, the frictional resistance generated between the cleaning blade and the endless belt cannot be sufficiently reduced. If the 10-point average roughness is 0.6 or more, it is difficult to obtain a reliable cleaning performance of the endless belt surface by the cleaning blade.
従って、本発明では、前記無端ベルトの外周面の無端長手方向に直行する幅方向の表面粗さを１０点平均粗さで０．２〜０．６μｍとして、クリーニングブレードとベルト外面との摩擦抵抗を安定的に低減して、クリーニングブレードの巻き込みを防止するとともに、前記クリーニングブレードによるベルト表面の確実なクリーニングを可能とする。 Therefore, in the present invention, the surface roughness in the width direction perpendicular to the endless longitudinal direction of the outer peripheral surface of the endless belt is set to an average roughness of 10 to 0.2 to 0.6 μm, and the frictional resistance between the cleaning blade and the belt outer surface is determined. Is stably reduced to prevent the cleaning blade from being caught, and the cleaning blade can surely clean the belt surface.
また、前記無端ベルトの無端長手方向に形成される溝間における稜線の起伏は極力平坦であることが望ましい。従って、本発明では、前記無端ベルトの外周面の無端長手方向の表面粗さが１０点平均粗さで、無端長手方向に直交する幅方向の表面粗さの１０点平均粗さの１/２以下であることが好ましい。 Moreover, it is desirable that the undulation of the ridge line between the grooves formed in the endless longitudinal direction of the endless belt is as flat as possible. Therefore, in the present invention, the surface roughness in the endless longitudinal direction of the outer peripheral surface of the endless belt is 10-point average roughness, which is 1/2 of the 10-point average roughness in the width direction perpendicular to the endless longitudinal direction. The following is preferable.
このため、前記無短ベルト外周面の無端長手方向の起伏が少なくなり、クリーニングブレードの巻き込みを無端ベルトの全周において安定的且つ効果的に防止するとともに、残留付着物の清掃を確実に行うことが可能となる。 For this reason, the endless undulation in the endless longitudinal direction of the outer surface of the endless belt is reduced, and the cleaning blade can be stably and effectively prevented from being wound around the endless belt, and the residual deposits can be reliably cleaned. Is possible.
〔表面粗さの測定方法〕
本発明の表面粗さの測定は、測定器として触針式表面粗さ計（小坂研究所製：ＳＥ−３４００）を用い、測定長０．８ｍｍ、スキャン速度０．１ｍｍ／ｓの条件で測定した。ここで、前記無端ベルトの外周面の無端長手方向に直行する幅方向の表面粗さの１０点平均粗さは、図１に示す矢印（Ｘ）の方向に測定器の触針をスキャンさせて１０点平均粗さを測定することにより得られた値である。また、前記無端ベルト外周面の無端長手方向の表面粗さの１０点平均粗さは、図１に示す矢印（Ｙ）の方向に測定器の触針をスキャンさせて１０点平均粗さを測定することにより得られた値である。
[Measurement method of surface roughness]
The surface roughness of the present invention is measured using a stylus type surface roughness meter (manufactured by Kosaka Laboratory: SE-3400) as a measuring instrument under the conditions of a measuring length of 0.8 mm and a scanning speed of 0.1 mm / s. did. Here, the 10-point average roughness of the surface roughness in the width direction orthogonal to the endless longitudinal direction of the outer peripheral surface of the endless belt is determined by scanning the stylus of the measuring instrument in the direction of the arrow (X) shown in FIG. It is a value obtained by measuring 10-point average roughness. The 10-point average roughness of the endless belt outer peripheral surface in the endless longitudinal direction is measured by scanning the stylus of the measuring instrument in the direction of the arrow (Y) shown in FIG. It is the value obtained by doing.
〔溝の形成方法〕
前記無端ベルト外周面に形成される溝は、砥粒を保持したフィルム（ラッピングフィルム）を前記無端ベルトに当接させて、前記無端ベルトを回転させるか、ラッピングフィルムを前記無端ベルトの回転方向に摺擦させることにより形成される。また、織毛に砥粒を保持させたブラシを用いて前記ラッピングフィルムと同様に溝を形成することも可能である。
[Groove formation method]
The groove formed on the outer peripheral surface of the endless belt is made to contact the endless belt with a film (wrapping film) holding abrasive grains and rotate the endless belt, or the wrapping film in the rotation direction of the endless belt. It is formed by rubbing. Moreover, it is also possible to form a groove | channel similarly to the said wrapping film using the brush which hold | maintained the abrasive grain to the wool.

[Recording medium conveying apparatus and image forming apparatus]
First, a recording medium conveying apparatus and an image forming apparatus provided with the endless belt will be described.
図２は本発明の記録媒体搬送装置及び該記録媒体搬送装置が適用される画像形成装置を示す。同図において１は矢印（図中反時計回り）に回転する像担持体としての感光ドラムである。前記感光ドラム１の周囲には回転方向上流側から順に、前記感光ドラム１を帯電する帯電器２、前記帯電器２により帯電された前記感光ドラム１に静電潜像を形成する露光装置３、前記感光ドラム１上の静電潜像をトナーにより現像する現像装置４、記録紙等の記録媒体を前記転写ドラム１の転写位置に搬送するとともに前記感光ドラム１上のトナー画像を記録媒体に転写する記録媒体搬送装置５、転写後の前記感光ドラム１上の残留トナー等を清掃するドラムクリーナ１０、が順次配置されている。また、図中、前記記録媒体搬送装置５の右方には画像が転写された記録媒体Ｐを定着する定着装置１３が配置されている。 FIG. 2 shows a recording medium conveying apparatus of the present invention and an image forming apparatus to which the recording medium conveying apparatus is applied. In the figure, reference numeral 1 denotes a photosensitive drum as an image carrier that rotates in the direction of an arrow (counterclockwise in the figure). Around the photosensitive drum 1, in order from the upstream side in the rotation direction, a charger 2 for charging the photosensitive drum 1, an exposure device 3 for forming an electrostatic latent image on the photosensitive drum 1 charged by the charger 2, A developing device 4 that develops the electrostatic latent image on the photosensitive drum 1 with toner, a recording medium such as recording paper is transported to a transfer position of the transfer drum 1, and a toner image on the photosensitive drum 1 is transferred to the recording medium. A recording medium conveying device 5 for performing the transfer and a drum cleaner 10 for cleaning residual toner and the like on the photosensitive drum 1 after the transfer are sequentially disposed. In the drawing, a fixing device 13 for fixing the recording medium P on which the image has been transferred is disposed on the right side of the recording medium conveying device 5.
前記記録媒体搬送装置５は、前記無端ベルト６Ａと、前記無端ベルト６Ａが巻き掛けられるローラ８ａ〜８ｃと、前記無端ベルト６Ａの外周面に当接して該ベルト６Ａ上の残留付着物を清掃するクリーニング部材であるところのクリーニングブレード７とが一体のユニットとして構成され、画像形成装置から着脱できるようになっている。また、前記クリーニングブレード７で清掃された残留付着物である廃トナーが収容されるように前記無端ベルト６Ａの下方には、廃トナーの収容空間が前記転写搬送装置５と一体に形成されている。 The recording medium conveying device 5 contacts the outer surface of the endless belt 6A, the rollers 8a to 8c around which the endless belt 6A is wound, and the endless belt 6A, and cleans the residual deposits on the belt 6A. The cleaning blade 7 serving as a cleaning member is configured as an integral unit and can be detached from the image forming apparatus. In addition, a waste toner storage space is formed integrally with the transfer / conveyance device 5 below the endless belt 6 </ b> A so as to store waste toner, which is residual deposits cleaned by the cleaning blade 7. .
前記クリーニングブレード７は、前記無端ベルト６Ａの下方であって、当該無端ベルト６Ａの回転方向（図中時計回り）に対してカウンター方向から当該無端ベルト６Ａの外周面に当接配置される。 The cleaning blade 7 is disposed below the endless belt 6A in contact with the outer peripheral surface of the endless belt 6A from the counter direction with respect to the rotation direction (clockwise in the drawing) of the endless belt 6A.
次に、前記記録媒体搬送装置５が適用される前記画像形成装置の動作について説明する。 Next, the operation of the image forming apparatus to which the recording medium conveyance device 5 is applied will be described.
前記帯電器２、前記露光装置３、現像装置４により前記感光ドラム１上で帯電、露光、現像工程が行われ、所定のトナー像が形成される。前記感光ドラム１上のトナー像が前記転写搬送装置５との間の転写部位に到達すると、感光ドラム１上のトナー像が記録媒体Ｐに転写される。そしてトナー像が転写された前記記録媒体Ｐは前記無端ベルト６Ａにそって搬送され、定着装置１３へと導かれて当該定着装置１３により加熱・加圧されてトナー像が記録媒体に定着される。 The charger 2, the exposure device 3, and the development device 4 perform charging, exposure, and development processes on the photosensitive drum 1 to form a predetermined toner image. When the toner image on the photosensitive drum 1 reaches the transfer portion between the transfer drum 5 and the transfer conveyance device 5, the toner image on the photosensitive drum 1 is transferred to the recording medium P. The recording medium P to which the toner image has been transferred is conveyed along the endless belt 6A, guided to the fixing device 13, and heated and pressurized by the fixing device 13 to fix the toner image on the recording medium. .
転写後に前記感光ドラム１上に残留する残留トナーはドラムクリーナ１０で清掃される。 Residual toner remaining on the photosensitive drum 1 after the transfer is cleaned by a drum cleaner 10.
また、前記無端ベルト６Ａの外面に付着したトナーや記録媒体の紙粉等は、前記クリーニングブレード７によって前記無端ベルト６Ａ外面から掻き落されて、前記無端ベルト６Ａの外周面が清掃される。 Further, toner adhered to the outer surface of the endless belt 6A, paper dust of the recording medium, and the like are scraped off from the outer surface of the endless belt 6A by the cleaning blade 7, and the outer peripheral surface of the endless belt 6A is cleaned.
前記無端ベルト６Ａの外周面には、無端長手方向に連続あるいは断続して伸びる溝が形成されている。このため、無端ベルト６Ａとクリーニングブレード７との間で発生する摩擦抵抗が低減され、クリーニングブレード７が無端ベルト６Ａの回転に巻き込まれて、当該クリーニングブレード７の先端が破損することや、当該クリーニングブレード７が前記転写搬送装置５の所定の取り付け位置から脱落すること等の不具合が生じることが無くなる。 A groove extending continuously or intermittently in the endless longitudinal direction is formed on the outer peripheral surface of the endless belt 6A. For this reason, the frictional resistance generated between the endless belt 6A and the cleaning blade 7 is reduced, the cleaning blade 7 is caught in the rotation of the endless belt 6A, the tip of the cleaning blade 7 is damaged, and the cleaning is performed.

ードがベルトに巻き込まれるまでのベルトの回転数を測定した。そして、実験結果からブレード巻込み特性を以下の３つのグレードに分類した。○：３０回転、△：１０回以上３０回未満、×：１０回未満
[Blade entrainment characteristics]
Each of the belts 101 to 110 obtained by the above production method is attached to the image forming apparatus shown in FIG. 3, and the toner is transferred only once to a belt having a width of 10 mm, and then a cleaning blade is brought into contact with the belt surface. Is rotated 50 times. At this time, the number of rotations of the belt until the cleaning blade was wound around the belt was measured. The blade entrainment characteristics were classified into the following three grades from the experimental results. ○: 30 rotations, Δ: 10 times or more and less than 30 times, ×: less than 10 times
[クリーニング特性]
図３に示した画像形成装置に上記の作成方法により得られたベルト１０１〜１１０をそれぞれ装着し、ベルトに対して１０ｍｍ幅の帯状にトナーを２回転写して、トナー全量をクリーニングブレードによって除去できるかを確認した。そして、実験結果からクリーニング特性を以下の３グレードに分類した。○：１００％トナーを掻き取れた。△：９５％以上掻き取れたが一部掻き取れずに残った。×：９０％未満しか掻き取れず、大半は残った。
[Cleaning characteristics]
Each of the belts 101 to 110 obtained by the above production method is mounted on the image forming apparatus shown in FIG. 3, and the toner is transferred twice to a belt having a width of 10 mm with respect to the belt. I confirmed. The cleaning characteristics were classified into the following three grades from the experimental results. ○: 100% toner was scraped off. Δ: 95% or more scraped off, but some remained without scraping. X: Only less than 90% was scraped off, and most remained.
表１から最表面に回転方向に連続あるいは断続する溝形状を形成することにより中間転写ベルトが、ブレード巻込み特性あるいはクリーニング特性において良好であることが分かる。特に、幅方向の十点平均粗さが０．２〜０．６μｍの場合にはクリーニングブレードの巻込み特性およびクリーニング特性が共に良好であることが分かる。 It can be seen from Table 1 that the intermediate transfer belt is excellent in blade winding characteristics or cleaning characteristics by forming a groove shape that is continuous or intermittent in the rotational direction on the outermost surface. In particular, it can be seen that when the ten-point average roughness in the width direction is 0.2 to 0.6 μm, both the winding characteristics and the cleaning characteristics of the cleaning blade are good.
更に、ベルト１０５および１０６と同様のベルトを、転写搬送ベルト、あるいは感光ベルトを備える画像形成装置に装着し、ブレード巻込み特性およびクリーニング特性を確認したところ、共に良好な結果を得ることができた。 Furthermore, when a belt similar to the belts 105 and 106 was mounted on an image forming apparatus equipped with a transfer conveyance belt or a photosensitive belt and the blade entrainment characteristics and cleaning characteristics were confirmed, good results were obtained for both. .
