本発明は、電子写真、静電記録及び静電印刷等における
静電荷像を現像するためのトナーに荷電を付与する部材
に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a member that charges toner for developing electrostatic images in electrophotography, electrostatic recording, electrostatic printing, and the like.
[従来の技術]
従来電子写真法としては、米国特許第2,297゜89
1 号、特公昭42−23910号公報及び特公昭43
−24748号公報などに種々の方法が記載されている

剤蒸気などで定着を行なうものである。[Prior art] As a conventional electrophotographic method, U.S. Patent No. 2,297°89
No. 1, Special Publication No. 42-23910 and Special Publication No. 43
Various methods are described in Japanese Patent No. 24748, etc., but in short, these methods apply a uniform electrostatic charge to a photoconductive insulating layer and irradiate the insulating layer with a light image to remove the electrostatic charge. An Hs image is formed, and then the latent image is developed and visualized using a fine powder called toner in this technology, and if necessary, the powder image is transferred to paper or the like, and then heated, pressurized, or with solvent vapor, etc. This is to fix the problem.
これらの電子写真法等に適応される現像方法としては、
大別して乾式現像法と湿式現像法とがある。前者はさら
に二成分系現像剤を用いる方法と、−成分系現像剤を用
いる方法に二分される。Development methods applicable to these electrophotographic methods include:
Broadly speaking, there are dry development methods and wet development methods. The former is further divided into a method using a two-component developer and a method using a -component developer.
二成分系現像方法に属するものには、トナーを搬送する
キャリヤーの種類により、鉄粉キャリヤーを用いるマグ
ネットブラシ法、ビーズキャリヤーを用いるカスケード
法、ファーを用いるファーブラシ法等がある。The two-component developing methods include a magnetic brush method using an iron powder carrier, a cascade method using a bead carrier, a fur brush method using fur, etc., depending on the type of carrier for conveying the toner.
又、−成分系現像方法に属するものには、トナー粒子を
噴霧状態にして用いるパウダークラウド法、トナー粒子
を直接的に静電!像面に接触させて現像する接触現像法
(コンタクト現像又はトナー現像ともいう)、トナー粒
子を静電潜像面に直接接触させず、トナー粒子を荷電し
て静電潜像の有する電界により該潜像面に向けて飛行さ
せるジャンピング現像法、磁性の導電性トナーを静電潜
像面に接触させて現像するマグネドライ法等がある。In addition, the -component-based development methods include the powder cloud method, which uses toner particles in a spray state, and the electrostatic method that uses toner particles directly. Contact development method (also called contact development or toner development) in which toner particles are developed by contacting with the image surface, and the toner particles are charged and developed by the electric field of the electrostatic latent image without directly contacting the toner particles with the electrostatic latent image surface. There are a jumping development method in which the toner is caused to fly toward the latent image surface, a magnetry method in which development is performed by bringing a magnetic conductive toner into contact with the electrostatic latent image surface, and the like.
これらの現像法に適用するトナーとしては、従来、天然
あるいは合成樹脂中に染料、顔料を分散させた微粉末が
使用されている。As toners applied to these developing methods, fine powders in which dyes and pigments are dispersed in natural or synthetic resins have conventionally been used.
例えば、ポリエチレンなどの粘着樹脂中に着色剤を分散
させたものを1〜30IL程度に微粉砕した粒子がトナ
ーとして用いられている。6ti性トナーとしてはマグ
ネタイトなどの磁性体粒子を含有せしめたものが用いら
れている。For example, particles obtained by dispersing a colorant in an adhesive resin such as polyethylene and pulverizing the particles to about 1 to 30 IL are used as toner. As the 6ti toner, one containing magnetic particles such as magnetite is used.
いわゆる二成分現像剤を用いる方式の場合には、トナー
は通常ガラスピーズ、鉄粉などのキャリアー粒子と混合
されて用いられる。In the case of a system using a so-called two-component developer, the toner is usually mixed with carrier particles such as glass beads and iron powder.
又、トナーは、現像される静電潜像の極性に応して正ま
たは負の電荷が保有せしめられる。Further, the toner is made to have a positive or negative charge depending on the polarity of the electrostatic latent image to be developed.
トナーに電荷を保有せしめるためには、トナーの成分で
ある樹脂のll擦帯電性を利用することもできるが、こ
の方法ではトナーの帯電性が小さいので現像によって得
られる画像はカブリ易く、不鮮明なものとなる。そこで
、所望の摩擦帯電性をトナーに付与するために、帯電性
を付与する染料、顔料、さらには荷電制御剤なるものを
添加することが行われている。In order to make the toner retain an electric charge, it is also possible to use the triboelectricity of the resin that is a component of the toner, but with this method, the toner's chargeability is small, so the image obtained by development is prone to fogging and is unclear. Become something. Therefore, in order to impart desired triboelectric charging properties to toners, dyes, pigments, and even charge control agents that impart charging properties are added.
しかしながら、これらの添加剤は、帯電性を付与するた
め、ある程度トナー表面に出ていなければならない、そ
のため、トナー同志の摩擦、キャリアとの衝突、静電潜
像保持体との摩擦などにより、トナー表面からこれらの
添加剤が脱落し、キャリアなどの汚染、静電潜像保持体
例えば感光体ベルトあるいはドラムなどの汚染などが生
じる。However, these additives must be present on the surface of the toner to some extent in order to impart charging properties. Therefore, the toner may be damaged due to friction between the toners, collision with the carrier, friction with the electrostatic latent image carrier, etc. These additives fall off from the surface, resulting in contamination of the carrier and the electrostatic latent image carrier, such as the photoreceptor belt or drum.
その結果、帯電性が悪くなり、画出し枚数が増すにした
がって劣化が進み、画像濃度が低下し、細線再現性、カ
ブリ性などが実用上問題となってくる。As a result, the charging property deteriorates, and as the number of images printed increases, the deterioration progresses, the image density decreases, and fine line reproducibility, fogging, etc. become practical problems.
これはトナーのバインダーと帯電性を付与する染料、顔
料あるいは荷電制御剤の親和性1分散性を向上させるこ
とによって改善することができるが、これらの添加剤の
親和性を高めるため表面処理をすると帯電付与性の低下
する場合が多く、また機械的にシェアを強くかけ細かく
分散すると。This can be improved by improving the affinity and dispersibility of the toner binder and the dye, pigment, or charge control agent that imparts chargeability, but if surface treatment is performed to increase the affinity of these additives, In many cases, the ability to provide a charge decreases, and if mechanical shear is applied strongly and finely dispersed.
トナー表面に出る添加剤の割合が減少し、帯電性が充分
に付与されない傾向となる。これらの理由で実用上充分
満足すべき帯電付与用添加剤は、きわめて限定され、実
用化されているものは少数にすぎない、特に将来白黒画
像のみならずカラー画像の需要の増大に対処するために
は、トナーに添加する添加剤は無色であることが好まし
く、現在この条件に合う実用化された添加剤はほとんど
無い。The proportion of additives appearing on the toner surface decreases, and charging properties tend to be insufficient. For these reasons, the number of charge-imparting additives that are sufficiently satisfactory for practical use is extremely limited, and only a small number of them have been put into practical use, especially in order to cope with the increasing demand for not only black and white images but also color images in the future. For this reason, it is preferable that the additive added to the toner be colorless, and there are currently almost no additives that have been put to practical use that meet this requirement.
