A.ポリエステル樹脂の製造
撹拌機と流出コンデンサーを取り付けた2Lの反応器に、テレフタル酸565g、ジメチル1,4−シクロヘキサンジカルボキシラート80g、無水トリメリット酸38g、エチレングリコール164g、2,2−ビス(4−ヒドロキシフェニル)プロパンプロピレンオキシド付加物330g、1,4−シクロヘキサンジメタノール138g、グリセロール22gと水素化されたポリブタジエンポリオールを充填させた。窒素気流下で反応器の温度を250℃まで徐々に上昇させ、副産物である水を反応器の外部に流出させながら、エステル化反応を行った。前記水の発生及び流出が終了された後、反応物を撹拌機、冷却コンデンサー及び真空システムが取り付けられた重縮合反応器に搬送した。そして、TiO2/SiO2共沈殿剤を酸成分全体に対して200ppm添加した。反応器の温度を250℃まで上昇させ、反応器の圧力を30分間50mmHgまで減圧しながら、低真空下において反応させて、過量のジオール成分を流出させた。次いで、反応器の圧力を0.1mmHgまで徐々に減圧し、高真空下において所定の撹拌トルクを示すまで反応を行った。縮重合反応終結10分〜1時間前にワックスを投入し、撹拌して混合した。得られたポリエステル樹脂のTgは58〜67℃であり、樹脂の軟化温度は150〜165℃であり、樹脂の酸価は1〜20KOHmg/gであり、樹脂中のゲルの量はポリエステル樹脂全体に対して2〜15重量%であった。
製造されたポリエステル樹脂53重量部、磁性体及び着色剤であるマグネタイト45重量部、及び荷電制御剤であるアゾ染料系の金属錯体2重量部を混合機により混合し、押出機において溶融混練した。次いで、押出された混合物をジェットミル粉砕機により微粉砕し、粉砕された粒子を風力分級機により分級した。次いで、粒子をシリカ1重量部及びチタンジオキシド0.2重量部にてコーティング処理して、体積平均粒子径が8〜9μmのトナー粒子を得た。製造したトナーのワックス分散性、貯蔵安定性、最小定着温度、オフセット温度、定着温度領域及びトナー画像濃度を測定して表1に示した。
