Abstract: 본 발명은 토너 조성물 및 이를 이용한 토너의 제조방법을 개시한다. 상기 토너 조성물은 결합수지 형성용 모노머, 착색제, 안정제, 전하제어제, 윤활제 및 중합개시제를 포함하고 있는데, 상기 안정제가, pH 10∼14로 조절된 증류수에 소수성 실리카를 분산시킨 다음, pH 6∼8로 조절하여 얻어진 결과물인 것을 특징으로 한다. 본 발명의 토너 조성물을 이용하면, 전하량, 평균입경 및 입경분포 특성이 개선된 토너를 제조할 수 있다. 특히 상기 토너 조성물이 계면활성제를 포함하는 경우에는 착색제 및 전하제어제의 분산성이 매우 향상된 토너를 얻을 수 있으며, 이러한 토너를 이용하면 종래보다 개선된 화상 품질을 얻을 수 있다.

Abstract: PURPOSE: Provided is a toner composition having improved dispersibility of a coloring agent and particle diameter characteristic. A method for preparing a toner by using the toner composition is also provided. CONSTITUTION: The toner composition comprises monomers for forming a binder resin, a coloring agent, a stabilizer, a charge controller, a lubricant and a polymerization initiator. The stabilizer is a product obtained by dispersing hydrophobic silica in distilled water having a pH controlled to 10-14 and then controlling the pH to 6-8. The toner composition further comprises an ionic surfactant. The mixing ratio of the monomers for forming a binder resin to silica on the basis of solid contents is 50:1 to 25:1.
