Abstract

본 발명은 균일한 전체화상을 얻고, 장기 복사, 프린팅시에도 화상농도가 높게 유지되며 비화상부의 오염이 적은 전자사진용 토너를 제조하기 위한 것으로, 수지, 하전제어제 및 착색제를 필수 구성성분으로 하는 토너에 유동성부여제와, 소수성 실리카로 표면처리된 지방산 금속염의 미세분말 또는 지방산 금속염과 수지를 용융혼합하여 얻은 미세분말을 소수성 실리카로 표면처리하여 외첨함을 특징으로 한다.The present invention is to produce an electrophotographic toner that obtains a uniform overall image and maintains a high image density even during long-term copying and printing, and has little contamination on non-image portions. Resin, charge control agent and colorant are essential components. Toner is characterized in that the fluidized agent and the fine powder of the fatty acid metal salt surface-treated with hydrophobic silica or the fine powder obtained by melt-mixing the fatty acid metal salt and the resin are surface treated with hydrophobic silica.
