Abstract

The present invention relates to a toner for developing an electrostatic image and a static charge controlling agent for a toner. The present invention provides a static charge controlling agent for a toner including a compound represented by the following General Formula 1 and a toner for developing an electrostatic image. [General Formula 1] (X is a quinoline compound having at least one substituent) In the present invention, a compound having a large molecular weight is used as a counter ion to increase the molecular weight of a charge controlling agent. Thus, problems concerning toxicity of a common quinoline compound static charge controlling agent may be solved. In addition, the melting point of the charge controlling agent is increased to prevent the adhesion thereof to a photosensitive article due to the elution from a toner during printing and the loss of image. Since the molecular weight of the charge controlling agent is large, the polarity of static charge and negative charge is large, and the quantity of electric charge is high. Charging stability is good and clear images may be obtained.

Description

정전하상 현상용 토너 및 토너용 정대전제어제 {Toner for developing electrostatic image and charge controlling agent}[0001] The present invention relates to toners for developing electrostatic images and toner toners for developing electrostatic image and charge controlling agents,

본 발명은, 전자사진과 같은 화상형성방법에 있어서 잠상을 현상화하기 위한 토너, 특히 정전하상 현상용 토너 및 이 토너에 사용되는 정대전제어제에 관한 것이다.TECHNICAL FIELD The present invention relates to a toner for developing a latent image in an image forming method such as electrophotography, in particular, a toner for developing an electrostatic latent image and a positive charge agent for use in the toner.

전자사진과 같은 화상형성방법은, 무기 감광체 또는 유기 감광체에 잠상을 형성하고 이것을 토너에 의해 현상, 종이 등에 전사 및 정착해 눈으로 볼 수 있는 화상을 얻는다. 감광체는 그 구성에 따라 정대전성 또는 부대전성을 갖는데, 감광체에 형성된 정전 잠상을 현상하기 위해서는 반대의 대전을 지닌 토너를 사용한다. 즉, 정대전성 감광체에서는 부대전성 토너를 사용하고, 부대전성 감광체에는 정대전성 토너를 사용한다. In an image forming method such as electrophotography, a latent image is formed on an inorganic photoreceptor or an organophotoreceptor, and the toner is transferred to and fixed on a developing paper or the like with a toner to obtain an image that can be visually seen. The photoreceptor has a positive or negative charge depending on its configuration. To develop an electrostatic latent image formed on a photoreceptor, a toner having an opposite charge is used. That is, the positively charged toner is used for the positively charged photoconductor and the positively charged toner is used for the non-charged photoconductor.

토너로는 천연 또는 합성 수지 중에 염료 또는 안료와 같은 착색제를 분산시킨 후 미분쇄한 입자를 사용한다. 토너의 제조방법으로는, 분쇄법, 용융분무법, 중합법 등이 있으며, 대부분 5~8㎛ 크기로 토너가 제조된다. 바람직하게는, 충분한 마찰대전성을 부여하기 위해 토너에 전하제어제를 포함시킨다. 정대전성 토너에는 정대전성 전하제어제를 사용하며, 부대전성 토너에는 부대전성 전하제어제를 사용한다. As the toner, finely divided particles are used after dispersing a coloring agent such as a dye or pigment in a natural or synthetic resin. The toner is produced by a pulverization method, a melt spraying method, a polymerization method, or the like, and most of the toner is produced in a size of 5 to 8 μm. Preferably, the charge controlling agent is included in the toner to impart sufficient triboelectric chargeability. Positive charge control agents are used for positively chargeable toners, and negative charge control agents are used for non-chargeable toners.

종래의 토너용 정대전제어제에는, 퀴놀린화합물(일본특허 제3267378호), 4급암모늄할라이드(일본특허 제3720092호), 4급암모늄할라이드와 카르본산 화합물(일본공개특허 평9-73192호) 등이 사용되고 있다. 종래에 사용되고 정대전제어제에는 다음과 같은 문제가 있다. 퀴놀린화합물의 경우는 퀴놀린화합물의 대이온으로 독성이 있는 금속 및 시안화합물을 사용하기 때문에 환경안정성에 문제가 있다. 4급암모늄할라이드, 4급암모늄할라이드와 카르본산 화합물의 경우는, 분자량이 작기 때문에 융점이 낮으며, 따라서 이를 함유하는 토너를 사용하여 인쇄할 때 프린터의 내부 온도(40~60℃)에 의해 인쇄 중에 토너로부터 용출되어 감광체에 부착되는 현상이 발생되며, 그로 인해 화상이 소실될 가능성이 매우 높다. Conventional tonicity antistatic agents include quinoline compounds (Japanese Patent No. 3267378), quaternary ammonium halides (Japanese Patent No. 3720092), quaternary ammonium halides and carboxylic acid compounds (JP-A No. 9-73192) Has been used. There are the following problems in the past. In the case of a quinoline compound, there is a problem in environmental stability because a metal and a cyanide compound which are toxic to a counter ion of a quinoline compound are used. Quaternary ammonium halides, quaternary ammonium halides and carboxylic acid compounds have a low melting point because of their low molecular weight, so that when printed using toners containing them, printing is performed by the internal temperature of the printer (40 to 60 ° C) A phenomenon that the toner is eluted from the toner and adhered to the photoreceptor is generated, and the possibility of image loss is very high.

일본 특허 제3267378호Japanese Patent No. 3267378 일본 특허 제3720092호Japanese Patent No. 3720092 일본 특허 제2822347호Japanese Patent No. 2822347 일본 공개특허 평9-73192호Japanese Laid-Open Patent Publication No. 9-73192
