Fluidity improver for positively-charging resin powder. |
摘要 |
<p>There is disclosed a hydrophobic silica-type micropowder comprising silica-type microparticles which have been treated with certain secondary or tertiary amine-functional silanes. When the micropowder is combined with a positively-charging resin powder, such as a toner, the fluidity of the resin powder is substantially increased and this improved fluidity is retained upon long term storage.</p> |
