비자성 일성분계 칼라 토너의 제조방법 {METHOD FOR PREPARING OF COLOR TONER BASED NONMAGNETIC ONE COMPONENT}Manufacturing method of nonmagnetic one-component color toner {METHOD FOR PREPARING OF COLOR TONER BASED NONMAGNETIC ONE COMPONENT}

본 발명은 비자성 일성분계 칼라 토너의 제조방법에 관한 것으로, 더욱 상세하게는 대전 분포가 좁고 고대전성을 가져 화상농도, 및 전사효율이 우수할 뿐만 아니라, 대전유지성을 현저히 향상시켜 장기신뢰성이 우수한 비자성 일성분계 칼라 토너의 제조방법에 관한 것이다.The present invention relates to a method for manufacturing a non-magnetic one-component color toner, and more particularly, has a narrow charge distribution and high conductivity, which not only has excellent image density and transfer efficiency, but also significantly improves charge maintainability and thus has excellent long-term reliability. A method for producing a nonmagnetic one-component color toner.

최근 칼라토너는 전자 사진 기술의 분야에서 수요가 증가되고 있으며, 이는 혼련 분쇄법, 현탁 중합법, 유화 중합법 등에 의해서 제조되고 있다. 상기 제조 방법 중 제조 안정성, 생산성 등의 관점에서 볼 때, 혼련 분쇄법이 주로 사용되고 있다.In recent years, color toner is increasing in the field of electrophotographic technology, and it is manufactured by kneading pulverization, suspension polymerization, emulsion polymerization, and the like. From the viewpoint of production stability, productivity and the like in the above production method, a kneading pulverization method is mainly used.

혼련 분쇄법이란 바인더 수지, 착색제, 전하제어제, 이형제 등의 토너 원료로 된 혼합물을 용융 혼련하여 얻어진 혼합물을 냉각한 후, 원하는 입경의 토너입자로 분쇄한 후, 분급을 하여 토너를 제조하는 방법이다. 여기서 현상용 토너는 마찰 대전법에 의해서 현상이 되고, 현상된 정전잠상의 극성에 따라서 정, 또는 부의 전하를 보유하게 된다. 토너의 대전 성능은 상기와 같은 내부 배합에 의해서도좌우되지만, 주로 첨가되는 첨가제에 의해서 많은 영향을 받기 때문에 첨가제의 배합, 및 첨가 방법의 변경에 의한 대전 성능의 향상을 꾀하고자 하였다.The kneading pulverization method is a method for producing a toner by cooling a mixture obtained by melt kneading a mixture of toner raw materials such as a binder resin, a colorant, a charge control agent, a mold release agent, and then grinding the mixture into toner particles having a desired particle size. to be. The developing toner is developed by the triboelectric charging method, and retains positive or negative charges depending on the polarity of the developed electrostatic latent image. Although the charging performance of the toner is also influenced by the above internal formulation, the charging performance of the toner is largely influenced by the additive to be added. Therefore, the charging performance of the toner is improved by changing the formulation of the additive and the addition method.

상기와 같은 첨가제에 의해서 토너가 현상될 때, 토너 공급부에서 현상 슬리브를 회전시키는 회전부에 관련된 저항이 경감되고, 대전 블래드(charging blade) 등에 토너가 융착되거나 토너끼리 서로 응집되는 일이 없도록 하고, 낮은 토오크로 균일하고 안정된 토너 층을 얻을 수가 있다.When the toner is developed by the above additives, the resistance associated with the rotating portion for rotating the developing sleeve in the toner supply portion is reduced, and the toner is not fused or charged together with a charging blade or the like, It is possible to obtain a uniform and stable toner layer with low torque.

특히 최근에는 컴퓨터의 출력장치로서의 프린터도 전자사진 방식의 레이저빔을 광원으로 한 프린터가 시장의 주류가 되고 있고, 소형화, 경량화, 및 고신뢰성을 중요시하고, 풀 칼라화의 수요가 급속하게 높아지고 있다. 이와 같은 배경으로부터, 전자사진장치로는 다양한 면에서 보다 심플한 구성을 가지며, 고화질과 고내구성을 필요로 한다. 따라서 토너에 있어서도 고전사 효율을 가지며, 장기적으로 균일한 현상특성을 가지는 토너를 필요로 한다.In particular, in recent years, printers as output devices for computers have become mainstream in the market with electrophotographic laser beams, and the demand for full colorization is increasing rapidly, with the emphasis on miniaturization, light weight, and high reliability. . From this background, the electrophotographic apparatus has a simpler configuration in various aspects, and requires high quality and high durability. Therefore, a toner having high high reflection efficiency and a uniform developing property in the long term is also required.

또한 첨가제가 토너입자의 표면에 균일하게 첨가되지 않을 경우에는 입자의 대전성이 서로 상이하여 균일한 화상을 얻을 수 없게 된다. 첨가제가 토너 표면에 균일하게 입혀진 경우에도 비자성 일성분계 토너에서는 인쇄를 진행함에 따라 토너에 가해지는 압력에 의해 토너-토너, 토너-대전 블래드(charging blade), 또는 토너-슬리브(sleeve) 간의 응집이 발생할 수 있고, 이러한 경우 장기적으로 화상이 흐려지고 불균일하게 되는 현상을 나타내게 된다.In addition, when the additive is not uniformly added to the surface of the toner particles, the charging properties of the particles are different from each other, so that a uniform image cannot be obtained. Even when the additive is uniformly coated on the surface of the toner, in the non-magnetic one-component toner, the pressure applied to the toner as the printing proceeds, the toner-toner, the toner-charging blade, or the toner-sleeve Agglomeration may occur, in which case the image becomes blurred and uneven in the long term.

따라서, 입자의 대전 분포가 좁고 고대전성을 가지며, 화상농도 및 전사효율이 우수할 뿐만 아니라, 대전유지성을 현저히 향상시켜 장기신뢰성이 우수한 비자성 일성분계 칼라 토너의 제조방법에 관한 것이다.Accordingly, the present invention relates to a method for producing a nonmagnetic one-component color toner having a narrow charge distribution of particles, high conductivity, excellent image density and transfer efficiency, and remarkably improving charge maintainability and excellent long-term reliability.

상기와 같은 문제점을 해결하고자, 본 발명은 대전 분포가 좁고 고대전성을 가지며, 화상농도와 전사효율이 우수할 뿐만 아니라, 동시에 대전유지성을 현저히 향상시켜 장기신뢰성이 우수한 비자성 일성분계 칼라 토너의 제조방법을 제공하는 것을 목적으로 한다.In order to solve the above problems, the present invention has a narrow charge distribution, high conductivity, excellent image density and transfer efficiency, and at the same time, remarkably improves charge maintainability, thereby preparing a nonmagnetic one-component color toner having excellent long-term reliability. It is an object to provide a method.

상기 표 5를 통하여, 본 발명에 따라 토너 모입자에 구형의 유기 분말을 코팅하여 부착시킨 후, 실리카를 코팅하여 부착시키는 2단계 코팅을 실시한 실시예 1 내지 18의 칼라 토너는 비교예 1 내지 18과 비교하여 화상농도, 전사효율, 및 장기성이 우수함을 확인할 수 있었다. 이는 구형의 유기 분말이 먼저 토너 모입자의 표면에 입혀져서 구형화한 효과를 나타내고, 이에 따라 토너 모입자 사이에 부착을 감소시킨 것을 알 수 있었다.Through the Table 5, the color toners of Examples 1 to 18, which were coated with silica and adhered to the toner base particles according to the present invention, and then coated with silica, were subjected to two-stage coating. Compared with the results, it was confirmed that the image density, the transfer efficiency, and the long term were excellent. It was found that the spherical organic powder was first coated on the surface of the toner base particles to give spherical effect, thereby reducing the adhesion between the toner base particles.

상기 표 6을 통하여, 구형의 유기 분말을 코팅하여 부착한 후, 실리카를 코팅하여 부착할 경우에도, 본 발명에 따라 1.2 ㎛ 이하의 평균입경을 갖는 구형의 유기 분말 0.2∼1.5 중량부, 및 7∼40 ㎚의 평균입경을 갖는 실리카 1∼3 중량부를 포함하는 실시예 19 내지 26의 칼러 토너의 화상 농도, 잔사효율, 및 장기성이 비교예 19 내지 50의 토너와 비교하여 우수함을 확인할 수 있었다.Through the above Table 6, even after coating and attaching the spherical organic powder, 0.2 to 1.5 parts by weight of the spherical organic powder having an average particle diameter of 1.2 μm or less in accordance with the present invention, and 7 It was confirmed that the image density, residue efficiency, and long-term properties of the color toners of Examples 19 to 26 containing 1 to 3 parts by weight of silica having an average particle diameter of -40 nm were superior to those of Comparative Examples 19 to 50.

상기에서 살펴본 바와 같이, 본 발명의 제조방법에 따르면 슬리브와 대전 블래드 사이에서 받는 압력을 줄여 용융, 또는 고체 부착을 줄임으로써 장기적으로 안정적인 화상을 얻을 수 있으며, 동시에 구형 유기 분말이 대전 블래드에 닿아 대전 블래드, 또는 슬리브 표면과의 마찰저항을 낮춤으로써 고전사효율, 및 고색도를나타내는 화상을 얻을 수가 있다. 또한 본 발명의 제조방법은 환경친화적이며, 특히 최근의 칼라화 경향에 따라 많이 이용되는 간접전사방식에서도 안정적으로 화상을 구현할 수 있는 장점이 있다.As described above, according to the manufacturing method of the present invention, a long-term stable image can be obtained by reducing the pressure received between the sleeve and the charging bladder to reduce melting or solid adhesion, and at the same time, the spherical organic powder is applied to the charging bladder. By lowering the frictional resistance with the charged blade or the surface of the sleeve, it is possible to obtain an image showing high high efficiency and high chromaticity. In addition, the manufacturing method of the present invention is environmentally friendly, and in particular, there is an advantage in that the image can be stably implemented even in the indirect transfer method which is widely used according to the recent colorization trend.
