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 함께 지방산 금속염의 미세분말 또는 지방산 금속염과 수지를 용융혼합하여 얻은 미세분말을 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 fine powder obtained by melt-mixing the fine powder of the fatty acid metal salt or the fatty acid metal salt and the resin together with the fluidizing agent.
