black specklesとは 意味・読み方・使い方

To provide such an electrophotographic photoreceptor that injection of positive charges from defects of an aluminum substrate can be prevented by incorporating titanium oxide fine particles subjected to the surface treatment to impart hydrophobicity into a charge generating layer, that the photoreceptor does not generate image defects in black speckles but has high sensitivity and low residual potential and that the photoreceptor is suitable for a digital copying machine and printer.例文帳に追加

疎水性に表面処理された酸化チタン微粒子が電荷発生層に含有されることにより、アルミ基体欠陥からの正電荷注入を防止する事が出来、黒班状の画像欠陥が発生せず、且つ高感度で残留電位が小さいデジタル複写機及びプリンター用に適した電子写真感光体を提供する。 - 特許庁
