詳しくは電子写真用トナー等に利用する電荷制御用樹脂
粒子の製造方法に関する。DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a method for producing charge control resin particles, and more particularly to a method for producing charge control resin particles used in electrophotographic toners and the like.
〈従来の技術〉
電子写真法、静電印刷法、静電記録法等において使用さ

き取っている。<Prior art> Development methods used in electrophotography, electrostatic printing, electrostatic recording, etc. develop an electrostatic latent image formed on a photoreceptor by charging and exposure with toner. The toner image is transferred onto a support such as a transfer paper, and the toner image is fixed on the support using a heating roller or a pressure roller to visualize the electrostatic latent image. In order to remove the toner remaining on the photoreceptor, the toner remaining on the photoreceptor is scraped off by a cleaning member such as a cleaning plate.
前記トナーはキャリアと混合して現像剤を構成する二成
分現像剤あるいはトナーのみによる一成分現像剤として
静電潜像の現像に用いられる。The toner is used for developing an electrostatic latent image as a two-component developer mixed with a carrier to form a developer, or as a one-component developer consisting only of toner.
そして、トナーを用いて、現像工程で原稿画像を忠実に

像へのトナーの付着量の減少による画像濃度の低下を防
止する必要がある。In order to faithfully reproduce the original image in the development process using toner, the amount of charge on each toner particle must be made uniform.
Prevents the migration of toner other than the electrostatic latent image due to uncharged particles, toner accumulation in the developing device due to excessively charged particles, and a decrease in image density due to a decrease in the amount of toner adhering to the electrostatic latent image. There is a need.
従来のトナーは、一般に、定着用樹脂を電荷制御剤等の
添加剤と共に加熱溶融して混練し、冷却後、粉砕して分
級する二とによって製造されている。Conventional toners are generally manufactured by heating, melting, and kneading a fixing resin together with additives such as a charge control agent, cooling, and then crushing and classifying the resin.
しかしなから、このような粉砕法によって製造されるト
ナーでは、トナーの粒度分布か広く、比較的粒度の大き

悪く、摩擦帯電性を支配する粒子表面に存在させるため
には、多量の電荷制御剤を添加する必要かあり、経済的
ではなかった。However, toner produced by such a pulverization method has a drawback that the toner particle size distribution is wide and contains particles with relatively large particle sizes. Also, whether a charge control agent is added to the fixing resin to control the triboelectric charging properties of the toner, or whether the charge control agent has poor dispersibility in the fixing resin and is present on the particle surface where it controls the triboelectric charging properties. However, it is necessary to add a large amount of charge control agent, which is not economical.
このような問題点を解消するために、以下のように種々
のトナーか提案されている。In order to solve these problems, various toners have been proposed as described below.

面に微小樹脂粒子を付着させたトナー。(2) Japanese Unexamined Patent Application Publication No. 62-22616226162 By heat-treating colored thermoplastic resin particles and fine resin particles whose outflow start temperature is higher than that of the resin particles by a flow tester, colored thermoplastic resin particles are produced. A toner with minute resin particles attached to the surface of resin particles.

となっていた。<Invention or problem to be solved> However, in all of these toners, the adhesion of the fine particles to the core particles is weak, so even if heat treatment is performed, the fine particles easily peel off, and in some cases, the fine particles may peel off. However, the result was that it did not adhere to the core particles at all. Furthermore, when fine particles are attached to core particles, there is a risk that the core particles will aggregate and partially produce toner with a coarse particle size, and such coarse toner will interfere with normal transfer and cause problems in the copied image. , which caused so-called white spots.
そこて、本出願人は、先に、樹脂のコア粒子と微小粒子
とにそれぞれ水系媒体中で互いに反対電荷に帯電する極

せる技術を開発した(特願昭63−130863号)。Therefore, the present applicant first imparted polarity to the core particles and microparticles of the resin so that they were charged to opposite charges in an aqueous medium, so that they adhered to each other in an aqueous medium, and in that state. We developed a technology for thermally fusing them together by heat treating them (Japanese Patent Application No. 130863/1986).

という問題かあ、った。However, when at least one of core particles and microparticles (usually core particles) is synthesized by a suspension polymerization method, a water-soluble polymer (
For example, when polyvinyl alcohol, starch, etc.) are used, the second water-soluble polymer is incorporated into the resulting polymer, making it highly hygroscopic, so when charge control resin particles are used as a toner, The drawback is that the charging performance is poor under high temperature and high humidity conditions. On the other hand, when a poorly water-soluble inorganic powder (calcium phosphate, calcium carbonate, magnesium carbonate, lium carbonate, etc.) is used as a dispersion stabilizer, the above-mentioned problems do not occur, but the slightly water-soluble inorganic powder used or interposed between the core particle and the microparticle,
The problem is that either the rain particles or their electrical attraction interferes with the adhesion, and therefore, even if heat treatment is performed in this state, the two do not fuse together sufficiently, resulting in a toner with poor charging properties. , it was.

The microparticles are fused to the surface of the core particle by heat treatment of the particles, and the suspension polymerization is carried out using a poorly water-soluble inorganic powder as a suspension stabilizer, and then a suspension of the resulting polymer is prepared. is adjusted to a pH value that dissolves the poorly water-soluble inorganic powder, and then the heat treatment is performed.

る。Therefore, in emulsion polymerization, it is preferable to perform so-called emulsifier-free emulsion polymerization without using an emulsifier. This polymerization method involves (1) using a reactive emulsifier, (2) polymerization of relatively hydrophilic monomers without an emulsifier using a persulfate initiator, and (2) water-soluble polymers, oligomers (such as polyhinyl alcohol, etc.). ) in place of the emulsifier, (1) using a decomposition type emulsifier, or (2) using a crosslinking type emulsifier. Either of these emulsifier-free emulsion polymerization methods can be employed to produce the microparticles of the present invention, or polymerization of a persulfate-based polymer having a negative charge in the same manner as the monomer having a sulfonic acid group is possible. It is particularly preferable to employ an emulsifier-free emulsion polymerization method using an initiator (for example, potassium persulfate, etc.) in view of charge control. The amount of the persulfate-based polymerization initiator added is suitably 1 to 5 parts by weight per 100 parts by weight of the monomer.

ア粒子を得るものである。Further, instead of the emulsion polymerization method, the microparticles may be created using a dispersion polymerization method. Here, the dispersion polymerization method refers to dissolving monomers together with additives such as colorants and mold release agents, and polymerization initiators in a solvent in which the monomers are dissolved but the polymer is not. Core particles are obtained by precipitating and polymerizing monomers while stirring in the presence of a dispersion stabilizer that stabilizes dispersibility.

付着粒子となり、いずれも好ましくない。The blending ratio of the core particle dispersion and the fine particle emulsion may depend on the ratio of the particle sizes of both, or may be 10% in terms of solid content.
It depends on whether the ratio is 0:0.1 to 100:20, but if the particles are smaller than this range, the coverage of the core particles with the microparticles is insufficient, and the particles between the core particles are not covered by the microparticles. Aggregates are generated due to cross-linking, and conversely, if the size is larger than this range, it becomes a small particle or surplus, and it is difficult to remove it. In some cases, the electrostatic attraction is insufficient, resulting in weakly adhered particles that peel off from the toner after being formed into a toner, which is not preferable.

Since the fine particles on the surface exhibit a negative charge due to triboelectric charging or the like, it can be suitably used as a negatively chargeable toner for electrostatic development. At that time, the chargeability of the resin particles can be controlled by appropriately changing the blending ratio of positively charged monomers or negatively charged monomers and other monomers in the aqueous medium used for the core particles and microparticles, respectively.
