Description
で表されるビスフェノールAのアルキレンオキサイド付加物が含有されていることが好ましい。
フローテスター(島津製作所、CFT-500D)を用い、1gの試料を昇温速度6℃/分で加熱しながら、プランジャーにより1.96MPaの荷重を与え、直径1mm、長さ1mmのノズルから押出する。温度に対し、フローテスターのプランジャー降下量をプロットし、試料の半量が流出した温度を軟化点とする。
示差走査熱量計(セイコー電子工業社製、DSC210)を用いて、試料0.01〜0.02gをアルミパンに計量し、200℃まで昇温し、その温度から降温速度10℃/分で0℃まで冷却したサンプルを昇温速度10℃/分で昇温し、吸熱の最高ピーク温度以下のベースラインの延長線とピークの立ち上がり部分からピークの頂点までの最大傾斜を示す接線との交点の温度とする。
JIS K0070の方法に基づき測定する。但し、測定溶媒のみJIS K0070の規定のエタノールとエーテルの混合溶媒から、アセトンとトルエンの混合溶媒(アセトン:トルエン=1:1(容量比))に変更した。
示差走査熱量計(セイコー電子工業社製、DSC210)を用いて200℃まで昇温し、その温度から降温速度10℃/分で0℃まで冷却したサンプルを昇温速度10℃/分で昇温し、融解熱の最大ピーク温度を融点とする。
測定機:コールターマルチサイザーII(ベックマンコールター社製)
アパチャー径:100μm
解析ソフト:コールターマルチサイザーアキュコンプ バージョン 1.19(ベックマンコールター社製)
電解液:アイソトンII(ベックマンコールター社製)
分散液:エマルゲン109P(花王社製、ポリオキシエチレンラウリルエーテル、HLB:13.6)5重量%電解液
分散条件:分散液5mlに測定試料10mgを添加し、超音波分散機にて1分間分散させ、その後、電解液25mlを添加し、さらに、超音波分散機にて1分間分散させる。
測定条件:前記電解液100mlに、3万個のトナー粒子の粒径を20秒間で測定できる濃度となるように、前記分散液を加え、3万個の粒子を測定し、その粒度分布から体積中位粒径(D50)を求める。
ポリオキシプロピレン(2.2)-2,2-ビス(4-ヒドロキシフェニル)プロパン2450g、ポリオキシエチレン(2.2)-2,2-ビス(4-ヒドロキシフェニル)プロパン975g、テレフタル酸963g、ドデセニルコハク酸343g、無水トリメリット酸298g及びジ2-エチルヘキサン酸錫20gを、窒素導入管、脱水管、攪拌器及び熱電対を装備した5リットル容の四つ口フラスコに入れ、窒素雰囲気下、230℃で反応率(反応生成水量/理論生成水量×100)が90%に達するまで反応させた後、8.3kPaにて所望の軟化点に達するまで反応を行い、樹脂A(ポリエステル)を得た。得られた樹脂の軟化点は150℃、ガラス転移点は63.0℃、酸価は7.1mgKOH/gであった。
ポリオキシプロピレン(2.2)-2,2-ビス(4-ヒドロキシフェニル)プロパン2100g、ポリオキシエチレン(2.2)-2,2-ビス(4-ヒドロキシフェニル)プロパン1300g、テレフタル酸1411g及びジ2-エチルヘキサン酸錫20gを、窒素導入管、脱水管、攪拌器及び熱電対を装備した5リットル容の四つ口フラスコに入れ、窒素雰囲気下、230℃で反応率(反応生成水量/理論生成水量×100)が90%に達するまで反応させた後、無水トリメリット酸57.6gを添加し、常圧にて所望の軟化点に達するまで反応を行い、樹脂B(ポリエステル)を得た。得られた樹脂の軟化点は100℃、ガラス転移点は60.9℃、酸価は12.3mgKOH/gであった。
表2に示す種類と量の結着樹脂及び離型剤、さらに負帯電性荷電制御剤「T-77」(保土ヶ谷化学工業社製)1.0重量部及びカーボンブラック「Mougul-L」(キャボット社製)5.0重量部を、予めヘンシェルミキサーを用いて混合後、二軸押出機により溶融混練し、衝突板式粉砕機、ディスパージョンセパレーターを用いて、粉砕、分級を行い、体積中位粒径(D50)8.0μmの負帯電性のトナーを得た。
オイルレス定着方式の非磁性一成分現像装置「MICROLINE 3010cW」(沖データ(株)製、A4 14ppm)を改造し、ヒートローラー温度を180℃に設定し、現像バイアスを振って紙上のトナー付着量を一定にした後、定着画像を得た。
定着率(%)=(テープ剥離後の画像濃度/テープ貼付前の画像濃度)×100
◎:定着率が80%以上
○:定着率が60%以上、80%未満
△:定着率が40%以上、60%未満
×:定着率が40%未満
試験例1と同様の装置を用い、ヒートローラー温度を160〜200℃に設定し、現像バイアスを振って紙上のトナー付着量を一定にした後、160℃から10℃刻みで200℃までヒートローラーの温度を上げながら定着画像を得た。各温度でのオフセットの有無を確認し、以下の評価基準に従って、耐高温オフセット性を評価した。結果を表2に示す。
◎:ヒートローラー温度が200℃でもオフセットの発生なし
○:ヒートローラー温度が180〜200℃でオフセット発生
△:ヒートローラー温度が160℃以上、180℃未満でオフセット発生
×:ヒートローラー温度が160℃でオフセット発生
