Description

【0001】
【発明の属する技術分野】
本発明は、静電荷像現像用トナーの接着力測定装置及び方法に関し、さらに詳しくは、紙等の画像形成体、定着ローラ、バックアップローラ等の定着部材の形状、材質、定着時の圧力、温度等の変化に対応する静電荷像現像用トナーの接着力のデータを得ることができる装置及び方法に関するものである。
【0002】
【従来の技術】
従来の公知文献及び公知技術としては、紙や段ボールを接着剤により接着した際の、接着力の測定に関して、第1試料片をクランプする固定台と第2試料片をクランプして固定台方向に進退する移動台と第2試料片に接着剤を塗布する接着剤塗布部があり固定台と移動台の重合部を押圧する圧締部があって固定台に引張力を測定する荷重測定装置を設け、移動台に圧締力を測定する荷重測定装置を備える接着強度を測定する装置が開示されている(例えば、特開平6−148063号公報・・・特許文献1参照)。
【0003】
また、粘着性を評価するタッキング試験機に関して、試料にプローブを押しつけて試料を引き上げる時の応力から粘着性を測定するためのプローブの制御手段、応力検出センサ、データ処理手段、試料台と、温度制御手段からなる装置が開示されている(例えば、特許第3100231号公報・・・特許文献2参照)。
【0004】
さらに、本出願人により、加熱及び温度設定ができるサンプル支持台部とこのサンプル支持台部に対して上下して測定サンプルの一部を持ち上げ剥離し、その剥離強度をフォースゲージにより測定する剥離強度測定部とを有する剥離強度測定装置を開示した(例えば、特開平10−332571号公報・・・特許文献3参照)。
【0005】
しかしながら、上記従来技術には、例えば特開平10−332571号公報に記載されているような内容においては、定着ローラの離型材料評価ツールの不備があり、同公報では定着ローラの開発の側面からの評価装置が提示されるが、トナーの機能評価の側面からは不充分であり、更に有用な評価方法と装置が望まれる。
【0006】
トナーの評価法としては、従来は長期のランニング試験や、ユニットによる評価が行なわれているが、こうした試験は時間を要する事と、本来のトナーと離型部材との離型機能を評価する方法としては外因からの誤差が極めて大きく絶対的な評価としては問題があり的確な評価が出来ない。またこうした評価は汎用性に乏しく適用範囲が狭い。
【0007】
微弱な剥離力を精度良く測定するためには、トナーを付着させた支持体を試料として用いることが出来ること、温度、圧力、加圧の時間、剥離速度等のパラメータを設定できることが必要な機能である。
【0008】
上記特開平10−332571号公報におけるトナーと定着ローラの剥離強度の測定では、主に剥離材料の評価を想定している。この公報では、トナーを支持体に定着させる機構については記載が無く、本発明の目的であるトナーの機能評価としては圧力、温度、時間等のパラメータが不充分である。また、支持体の端部を保持して引上げる方式のため、接着力が弱い場合には支持体のこしによって自己剥離してしまう場合があり、微弱な剥離力の測定にはやや難がある。
【0009】
また前記の特許第3100231号公報では、粘着性を評価するタッキング試験機に関するものであり、試料にプローブを押しつけて試料を引き上げる時の応力から粘着性を測定するものである。プローブの制御手段、応力検出センサ、データ処理手段、試料台と、温度制御手段からなる装置では、支持体を支持する機構が無く、支持体にトナーを定着させた時の剥離力を測るという目的には適用できない。
【0010】
さらに、粉体を直接試料台に乗せて試験すると、測定を開始するまでの熱履歴や、トナーの密度の違いによるばらつきなどにより、測定精度に問題がある。また、加熱のパラメータに対する機能が無く、支持体にトナーを定着させた時の剥離力を測るという目的には適用できない。
【0011】
接着状態から測定するため、定着のように極弱い接着力では90°、180°の剥離角度の場合、接着力が弱いために支持体のこしによって自己剥離してしまう場合があり、微弱な剥離力の測定には難がある。特に、ワックス入りのトナーのような場合、加熱時のワックスの動きが品質を左右する場合もあり、このようなワックスの動きの機能の評価には不向きである。

即ち、本発明は、上記の課題解決のために、トナー画像の像形成支持体への接着力を測定すべく、支持体に定着されたトナーの、定着部材に対する付着・接着性を剥離力で測定し、トナーの性能を定量的に捉える手段の検討の結果、本発明の上記測定装置とそれによる評価方法が有効であることを見い出し、本発明を完成するに至ったものである。
【0027】
【発明の実施の形態】
以下、図面により本発明の実施の形態を詳細に説明する。
図1は本発明の実施例の測定装置構成全体を示すもので、離型部材(受板プレート)を支持し任意の温度に加熱、保温、温度計測ができる定着用加熱ユニットAと、試料である像形成支持部材を保持し定着用加熱ユニットAとの接触位置に配置された加圧端子ユニットBと、該加圧端子ユニットBを下降上昇させる構成を有し、定着用加熱ユニットAはステッピングモーター9などで、待機位置、測定位置に移動する機構を有する。加圧端子ユニットBは錘6の重量で設定される圧力で定着用加熱ユニットAの受板プレート5に加圧され、定着用加熱ユニットAで設定した温度で熱せられる。
【0028】
加圧端子ユニットBの下降時は、ステッピングモーター7で錘6が下降し同時にステッピングモーター8で加圧体が定着用加熱ユニットAの受板プレート上に下降する。上昇時にはステッピングモーター7で錘6が上昇し同時にステッピングモーター8で加圧端子ユニットBが上昇し、同時に像形成支持部材1と定着用加熱ユニットAの受板プレート5との間の剥離の負荷がロードセルにより計測され、データは電算機Cに送られ演算処理が行なわれる。電算機Cは装置のパラメータを設定し測定動作を指示する機能と、データ転送、データ処理・解析の機能を持つ。
【0029】
なお、図1の定着用加熱ユニットAは、2組、図1に示されているが、待機時と測定時の位置を同時に示してあり、実際には1組である。定着用加熱板ユニットAは待機時右側に位置している。これは定着用加熱ユニットの取替えや、受板プレート5の交換、清掃、加圧端子ユニットBで像形成支持部材をセットする時などの作業性を考慮し、更に試料が試験直前まで温度の影響を受けない位置で待機させることが好ましく、移動式としたものである。
測定時に定着用加熱板ユニットAは、ステッピングモーター9などの機構により加圧端子ユニットBの下まで移動する。移動レール10で位置が試験時に確実に固定される機構になっている。
【0030】
図1の定着用加熱板ユニットAは、内部に加熱手段を有する加熱ユニット4と、その上に保持される定着用加熱ユニットAの受板プレート5で構成される。定着用加熱の受板プレート5は図示されていないストッパーなどで上下左右にズレが生じないように固定される。加熱ユニットは必要に応じて加圧力を測定できるロードセル等も設置する。
【0031】
図1の加圧端子ユニットBは、加圧端子部材3と加圧端子の保持部、像形成支持部材1を保持する試料クランパー2で構成され、像形成支持部材1を試料クランパー2で保持させる。
像形成支持部材1には粉体トナーを付着し付着面は下向きに、加圧体部の加圧端子部材3の下降により定着用加熱ユニットAと接触する位置にセットする。加圧端子部材3は保持部に前後左右のアソビを持たせる形で取りつけられており、下降・加圧時に受板プレート5と片寄り無く密着するようになっている。
【0032】
図1の電算機Cは、装置のパラメータ制御、指示、データ転送、データ処理、データ解析などのプログラムと機能を持つPCで、自動測定、手動測定それぞれに対応できるプログラムとなっている。
【0033】
図1の剥離駆動部D部は、水平剥離、90°の剥離時の測定に使用するユニットで、試料クランパー11、水平方向の引張で使用するロードセルと駆動部で構成される。水平の剥離時には引張の負荷をロードセルにて計測する。90°剥離時には支持体の片側を支持する機構(固定)を持つが、必要に応じて上下方向にも駆動する機能となっており、汎用性をもたせている。
【0034】
図2において、像形成支持部材1は粉体トナーを付着させた試料で、加圧端子ユニットBが下降した時に、定着用加熱ユニットAに設置された受板プレート5に接触し、設定した圧力と温度で定着されるように、加圧端子部材3の部分にトナー付着面が下向きになるように位置決めし、試料クランパー2でたるみ無くセットされる。測定を開始すると図2aのように加圧端子Bユニットが下降して設定された温度と加圧力で定着され、設定された時間保持した後、図2bに示すように、設定された速度で上昇し、負荷が計測される。垂直に上昇するため、接地面は同時に引上げられる。
【0035】
図3のように、剥離方法を一端から90°の角度でピール剥離とする場合には、90°剥離ユニットとして、剥離駆動部Dを用い、試料クランパー11で一端を保持し、引上げる一端を加圧端子ユニットBの試料クランパー2で、図3aに示すように保持する。加圧端子ユニットBが設定された速度で図3bに示すように上昇しながら90°剥離の負荷が計測される。
【0036】
図4に示すように、定着用加熱ユニットAの受板プレート5に対し水平に横方向に引っ張り、剪断負荷を測定する場合には、剥離駆動部Dの試料クランパー11で試料を保持し、加圧端子ユニットBの下降による定着が行われた後、加圧端子ユニットBが上昇して圧力が解除された後、設定された速度で引っ張り、負荷を計測する。
【0037】
図5に定着用加熱ユニットA上部の定着加熱用の受板プレート5が平板である定着用加熱板部Aユニットを示す。
図6は定着用加熱ユニットA上部の受板プレート5が曲面である定着用加熱ユニットAを示す。
【0038】
温度コントロールはPID制御などでヒーター温度が制御され、±2℃以内が望ましく、±1℃以内が更に望ましい。また、加熱を停止して温度下降の勾配を持たせた試験もできる。温度検知は接触、非接触でいずれかで検知されるが精度の面から接触型が好ましい。
【0039】
測定に使用されるフォースゲージは汎用のものが使用可能であるが、精度の面からロードセルを用いることが望ましい。
【0040】
データは演算され図7の例で示されるような、最大値、最小値、平均値、データ数のほか、全データからの各種解析データが計算されてアウトプットされる。
【0041】
図1の機構を有する静電荷像現像用トナーの接着力測定装置による測定の一例を示す。
像形成支持部材にトナーを1.5×1.5cmの面積で1.0mg/cmの付着量で付着させ、図2に示すようにトナー面を下向きにして加圧端子部材3と定着用加熱ユニットAの受板プレート5の接触部分にトナー面が合うように位置決めして試料クランパー2で保持させた。加圧端子部材3はシリコーンの弾性体とした。
【0042】
次に電算機C(以下PCとする)のプログラムでロードセルの風袋除去を行ない、測定パラメータとして温度を100℃、加圧体の下降スピードを20mm/sec、加圧時間を10sec、上昇スピード(剥離速度)を10mm/secに設定した。また、加圧力は錘により0.1MPaとなるようにした。ヒーターはPID制御により±2℃以内で制御される。ヒーターが安定状態となった時点でプログラムの測定ボタンを押下する。定着用加熱ユニットAはモーター9により設定されている往路を75mm/secのスピードで測定位置に移動レール10に沿って移動する。加圧体の降下が始まる。ステッピングモーター7により錘6が降下し、ステッピングモーター8により加圧体が定着用加熱ユニットA上に降下する。この動作は同時に行なわれる。加圧状態に入り、10sec後、ステッピングモーター7により錘6が上昇、ステッピングモーター8により加圧体が設定された10mm/secのスピードで上昇する。同時にロードセルにより荷重の測定が開始され、5msecの間隔でデータがPCへ転送される。錘6はホーム位置に戻り、加圧体は設定した距離25mmを移動した時点で停止する。定着用加熱ユニットAを待機位置に戻すため、PC上のスイッチを押下するとステッピングモーター9によって復路100mm/secで戻る。測定終了した試料は試料クランパーから取り外す。PC上では転送されたデータが演算され、最大値、最小値、平均値、データ数のほか、全データからの各種解析データが計算されてアウトプットされる。
【0043】
この方法で、支持体(像形成支持部材)としての電子写真用複写紙(リコー社製、type6200ペーパー)上に、WAXを含有したトナーを付着させ、定着用加熱ユニットAにフッ素系樹脂であるPFAコート層を持つ離型部材のテストピースをセットし測定を行なった。事前の長期ランニング試験でオフセット品質に差のあったサンプルで比較したところ、各5回の試験でのサンプルの剥離強度のピーク値の差は0.45〜0.48Nの範囲で計測された。
【0044】
本発明の評価装置・方法を適用すれば、任意の離型部材(受板、定着ローラ等に相当)、トナーの試験を様々なパラメータで容易に行なえ、汎用性があり、短時間で、また実機評価で問題とされる外因の誤差が少なく固定的な従来の方法よりも優れた評価が行なえるようになる。
【0045】

The present invention relates to an electrostatic force image developing toner adhesion measuring apparatus and method, and more specifically, the shape and material of an image forming body such as paper, a fixing roller and a backup roller, and pressure and temperature during fixing. The present invention relates to an apparatus and a method capable of obtaining data of adhesive force of an electrostatic image developing toner corresponding to a change in the above.
[0002]
[Prior art]

A load measuring device that has a moving base that moves forward and backward and an adhesive application part that applies adhesive to the second sample piece, and a pressing part that presses the overlapping part of the fixing base and the moving base, and measures the tensile force on the fixed base. An apparatus for measuring an adhesive strength provided with a load measuring device for measuring a pressing force on a moving table is disclosed (for example, see Japanese Patent Application Laid-Open No. 6-148063 ... Patent Document 1).
[0003]
In addition, with regard to tacking test machines for evaluating adhesiveness, probe control means, stress detection sensor, data processing means, sample stage, and temperature for measuring adhesiveness from the stress when the probe is pushed up against the specimen and pulled up. An apparatus comprising a control means is disclosed (for example, refer to Japanese Patent No. 3100231 ... Patent Document 2).
[0004]
Further, the present applicant can raise and lower the sample support base part that can be heated and set the temperature, and part of the measurement sample is lifted and peeled off, and the peel strength is measured by a force gauge. A peel strength measuring device having a measuring part has been disclosed (for example, see Japanese Patent Application Laid-Open No. 10-332571... Patent Document 3).

However, the above-described prior art has deficiencies in a fixing roller release material evaluation tool in the contents described in, for example, JP-A-10-332571. However, it is insufficient from the viewpoint of toner function evaluation, and a more useful evaluation method and apparatus are desired.
[0006]
Conventionally, as a toner evaluation method, a long-term running test or evaluation by a unit has been performed. However, such a test requires time and a method for evaluating a release function between an original toner and a release member. As a result, errors from external factors are extremely large, and there is a problem as an absolute evaluation, and an accurate evaluation cannot be made. In addition, such evaluation is not versatile and its application range is narrow.
[0007]
In order to accurately measure weak peeling force, it is necessary to be able to use a support with toner attached as a sample, and to set parameters such as temperature, pressure, pressurization time, peeling speed, etc. It is.
[0008]
In the measurement of the peel strength between the toner and the fixing roller in the above-mentioned JP-A-10-332571, the evaluation of the release material is mainly assumed. This publication does not describe a mechanism for fixing the toner to the support, and parameters such as pressure, temperature, time, etc. are insufficient for functional evaluation of the toner which is the object of the present invention. In addition, since the end portion of the support is held and pulled up, if the adhesive force is weak, the support may be self-peeled by the strain of the support, and measurement of the weak peel force is somewhat difficult.
[0009]
Japanese Patent No. 3100231 relates to a tacking tester for evaluating adhesiveness, and measures adhesiveness from stress when a probe is pressed against a sample and the sample is pulled up. The apparatus comprising the probe control means, stress detection sensor, data processing means, sample stage, and temperature control means has no mechanism for supporting the support, and the purpose is to measure the peeling force when the toner is fixed on the support. Not applicable to
[0010]
Further, when the powder is directly placed on the sample stage and tested, there is a problem in measurement accuracy due to a thermal history until the measurement is started and a variation due to a difference in toner density. Further, it does not have a function for heating parameters and cannot be applied to the purpose of measuring the peeling force when toner is fixed on a support.
[0011]
Since it is measured from the adhesion state, if the adhesion angle is 90 ° or 180 ° with a very weak adhesion force such as fixing, the adhesion force is weak and the substrate may be peeled off by the strain of the support. There are difficulties in measuring. In particular, in the case of toner containing wax, the movement of the wax during heating may affect the quality, and is not suitable for evaluating the function of the movement of the wax.
