Description
本発明は、多色及び単色又はブラックの画像形成に適した粉末状の乾燥電子写真トナーに関する。
暗部は画像形成するカラーを覆うので、多色画像形成に適したトナーでは暗成分の使用が避けられる。シリコンカーバイドは暗く、通常、例え少量であってもトナー粒子の表面成分として使用することができない(多くの場合に、超微粒子添加剤又はEPAと言われる)。
バインダとしてのポリエステル樹脂と、着色剤としての顔料と、電荷制御成分と、剥離剤としてのワックスと、流れを改善し、かつ、ドクターブレードのような接触要素から掻き取るための超微粒子添加剤と(EPAs)を有する、通常の従来型の乾燥微粒子の静電トナーでは、1)一方のEPAが、酸化アルミニウムで表面処理された親水性のルチル型針状酸化チタンであり、2)一方が低表面積で他方が高表面積の二つのシリカが、トナー
のバルク内で混合され、3)電荷制御要素が、有機ホウ素錯体の負電荷制御剤とアルミノ
シリケート化合物の第4アンモニウム塩との混合物である。
下記の詳細な実施態様の成分は全て固体状であり、容易に機械的に混合され、粉末状に粉砕され、次いで分級される。
