NONMAGNETIC ONE-COMPONENT SYSTEM TONER COMPOSITION |
摘要 |
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.
