Description
実施例1〜6、比較例1〜4
まず、軸体となる芯金〔直径6mm、ステンレス(SUS304)製〕と、導電性弾性層形成材料としてSBR(JIS−A硬度20°)100質量部(以下単に部と記載する)にカーボンブラック10部を添加したものとを準備した。そして、これらを用い、金型成形により、上記芯金外周面に導電性弾性層が形成されたベースロールを作製した。次に、N−メトキシメチル化ナイロン(帝国化学社製、トレジンEF30T)100部と、導電剤(ケッチェンブラックEC、ケッチェンブラック・インターナショナル社製)20部とを、MEK400部と混合することにより、軟化剤移行防止層用材料を調製した。一方、NBR(日本ゼオン社製、ニポールDN401)100部と、四級アンモニウム塩(和光純薬社製、TBAHS)1部と、アセチレンブラック(電気化学工業社製、デンカブラックHS−100)30部と、ステアリン酸(花王社製、ルナックS30)0.5部と、亜鉛華(堺化学工業社製)5部と、加硫助剤(三新化学社製、サンセラーCZ−G)1.07部と、加硫助剤(大内新興化学社製、ノクセラーBZ−P)0.49部と、硫黄(鶴見化学工業社製、サルファックスPTC)1部とを混合・攪拌し、抵抗調整層用材料を調製した。そして、これらを用い、前述の方法に準じて、上記ベースロールの外周面に、軟化剤移行防止層および抵抗調整層を順次、形成することにより、軸体の外周に導電性弾性層、軟化剤移行防止層および抵抗調整層が形成されてなるロール基体を作製した。なお、このロール基体の導電性弾性層の厚みは3mmであり、軟化剤移行防止層の厚みは5μmであり、抵抗調整層の厚みは150μmであった。
実施例1の保護層に、樹脂粒子を添加しなかった。それ以外は、実施例1と同様の材料を用いて同様の手順で帯電ロールを作製した。
帯電ロールを片側荷重2Nのばねで感光ドラム径がφ12mmのカートリッジに圧接し、温度40℃×湿度95%の高温高湿環境下に4日間放置した。その後、温度23℃、湿度53%にて、Sagem社製MF5401プリンターに帯電ロールを組み込んで、2dotピッチハーフトーン画像(600dpi)を出力し、当接跡の画像スジの有無を目視で調べた。画像スジが全く認められないものを◎、画像スジがほとんど認められないものを○、薄い画像白スジがあったものを△、明確な画像白スジがあったものを×として評価した。
Sagem社製MF5401プリンター用カートリッジを用い、温度32.5℃×湿度85%の環境下で24時間以上養生後、感光ドラムの回転数が60rpmで1200Vの電圧を印加後、ドラムが2周目の帯電量平均を測定した。
Sagem社製MF5401プリンターを用い、温度32.5℃×湿度85%の環境下で24時間以上養生後、5%文字文書の実機間欠耐久印刷を1500枚実際に印刷した。耐久印刷前と後の廃トナー容器の重さを測定して、耐久印刷の際の廃トナー量(絶対量)を求めた。廃トナー量は、印字に利用されなかった感光ドラム転写トナーの量であり、廃トナー量が多い程、トナー消費量が多いと云える。また比較例5は保護層6に樹脂粒子を含有していないので、トナー消費量が最も少ない。そこで表1に保護層6に樹脂粒子を添加しなかった比較例5の廃トナー量との差を廃トナー量の[粒子無しとの差]として示した。
2 軸体
5 抵抗調整層
6 保護層
