定性と持続性に顕著に優れ、とくにカラートナー
に好適な電荷制御剤を含有したトナーに関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a toner for developing electrostatic images in electrophotography, and more specifically, the present invention relates to a toner for developing electrostatic images in electrophotography. The present invention relates to a toner containing a charge control agent which has remarkable properties and is particularly suitable for color toners.

ナー粒子を前記静電荷像に静電的に付着させるこ
とにより達成される。 Generally, in electrophotography, electrostatic recording, electrostatic printing, etc., visualization of an electrostatic charge image involves applying toner particles, which have been given a charge of opposite polarity to the latent image charge of the electrostatic charge image by frictional charging, to the electrostatic charge image. This is achieved by electrolytic deposition.

御剤が添加される。 Such toner contains a coloring agent such as carbon black in a binder resin such as an acrylic resin or an epoxy resin, and a charge control agent is added so that a desired charge is imparted to the toner by the frictional charging. Ru.
こうした電荷制御剤としては、例えばオイルブ
ラツク、ニグロシン、クロムイエロー、フタロシ
アニンブルー等の顔染料が知られ、とくに負帯電
性の電荷制御剤として各種の含金属染料が使われ
ていることは周知のとおりである。 Facial dyes such as oil black, nigrosine, chrome yellow, and phthalocyanine blue are known as such charge control agents, and it is well known that various metal-containing dyes are used as negatively chargeable charge control agents. It is.
これらの顔染料は、トナー粒子へ荷電を付与す

色の顔染料を電荷制御剤として用いることができ
ないのは当然である。そこで無色又は実質的に無
色と見做し得る程度に淡色の電荷制御剤が是非と
も必要になる。 Although these facial dyes have excellent performance in imparting charge to toner particles, one of their essential deficiencies is that they are colored substances. That is, the color toner used in color electrophotography must have a specific clear hue such as red, blue, magenta, cyan, and yellow. However, as a method of imparting a desired charge to these colored toner particles, it is natural that the above-mentioned colored facial dyes cannot be used as a charge control agent. Therefore, a charge control agent that is colorless or light in color to the extent that it can be considered to be substantially colorless is absolutely necessary.

響を与えるのである。 Furthermore, although these conventional toners containing face dyes exhibit good development characteristics initially, they have a problem of short lifespan in continuous copying. The reason for this is that facial dyes as charge control agents have poor compatibility or affinity with many binder resins.
In other words, in the process of melting and kneading the toner, it is difficult for the facial dye to be uniformly dispersed in the binder resin, so in the process of pulverization, not only particles with non-uniform components are created, but also fine particles consisting only of dyes and pigments. can. The presence of these charge control fine particles has a serious adverse effect on the life of the developer.
本発明は上記の事情に鑑みてなされたものであ

供するものである。 The present invention has been made in view of the above circumstances, and uses a styrene-maleic acid copolymer resin as a binder resin, a colorant, and a negatively chargeable charge control agent based on 100 parts by weight of the binder resin. The object of the present invention is to provide a toner for developing an electrostatic image, characterized in that it contains 0.1 to 50 parts by weight.

に限定されるものではない。 The styrene-maleic acid copolymer resin referred to in the present invention is, for example, a resin in which a part of the polymerization reaction system of styrene and maleic acid is esterified with an alkyl ether such as diethylene glycol monobutyl ether, and has the following structural formula. things are applied. However, the present invention is not particularly limited to the partially esterified styrene-maleic acid copolymer resin having such a molecular structure.

用される。 Such a styrene maleic acid copolymer resin is blended in an amount of 0.1 to 50 parts by weight per 100 parts by weight of the binder resin. In this case, if the amount is 50 parts by weight or more, the amount of charge will increase during continuous copying, resulting in poor developability, and if the amount is less than 0.1 part by weight, the effect of charge control cannot be achieved. As the binder resin, polystyrene, styrene acrylate copolymer, styrene butane diene copolymer, polyester resin, epoxy resin, etc., which are usually used as toner resins, can be used alone or in combination. In the case of pressure fixing toners, waxes, higher fatty acids, polyolefins, olefin copolymers, etc. are used as the binder resin. The styrene-maleic acid copolymer is blended for the purpose of controlling the charge of toner particles, but depending on the amount blended, it also necessarily has a function as a binder resin. As the coloring agent, various organic pigments such as monoazo, copper phthalocyanine, and quinacridone, and carbon black are used, and when the present invention is implemented as a one-component toner, a colored magnetic material such as magnetite is used.
