    • PURPOSE: A non-magnetic monocomponent toner composition is provided to prevent the bonding of a toner to the blade of a development roller and to improve the control effect of PCR contamination. CONSTITUTION: A non-magnetic monocomponent toner composition comprises a non-magnetic toner mother particle including a binding resin; a hydrophobic silica having a specific surface area of 20-80 m^2/g; a hydrophobic silica having a specific surface area of 130-230 m^2/g; and a titanium oxide having an average particle diameter of 10~100 nm. The binding resin comprises 45-87 parts by weight of a resin for toner, and 10-30 parts by weight of an acrylate-styrene-acrylonitrile resin based on 100 parts by weight of the non-magnetic toner mother particle. The non-magnetic toner mother particle has an average particle diameter of 5-12 micrometers.
    • 目的:提供非磁性单组分调色剂组合物,以防止调色剂与显影辊的叶片结合,并提高PCR污染的控制效果。 构成:非磁性单组分调色剂组合物包含包含粘合树脂的非磁性调色剂母粒; 比表面积为20-80m 2 / g的疏水性二氧化硅; 比表面积为130-230m 2 / g的疏水性二氧化硅; 和平均粒径为10〜100nm的氧化钛。 粘合树脂包含45-87重量份的用于调色剂的树脂和基于100重量份非磁性调色剂母粒子的10-30重量份的丙烯酸酯 - 苯乙烯 - 丙烯腈树脂。 非磁性调色剂母粒的平均粒径为5-12微米。
