いる。[Prior art 1 Conventionally, color developer is dispersed as ultrafine particles in an aqueous solvent, and after adjusting the binder and additives, it is applied to the paper that is made to form a special paper called a color developer sheet. Was. This image forming technique using a color developer sheet is described in Japanese Patent Laid-Open Nos. 58-88739, 30537-1983, 137944-1980, and the like.

系である。Here, image forming technology refers to two or more components isolated from each other that are released from isolation by physical external forces such as pressure or temperature changes, and react with each other to produce optical changes and light. For example, a microcapsule whose mechanical breaking strength changes when irradiated with light refers to all functions that cause a change in the absorption area or absorption intensity and are recorded according to the external direction. By superimposing the photosensitive pressure recording TT medium supported on an arbitrary medium and the color developer Sea F, and developing under pressure, microcapsules with different mechanical breaking strengths are selectively cleared, and the microcapsules are separated into microcapsules. A colorless or slightly colored dye contained therein, or a substance that can cause the dye to develop color by reacting with the dye precursor, i.e., reacts with the developer, which is a dye receptor, to form a developed image on the developer sheet. It is an image forming system that

体上に塗布できるような顕色剤トナーが提案された。[Problems to be Solved by the Invention] However, the object on which images are to be formed is not only the developer sheet but also various arbitrary media. Therefore, a color developer toner has been proposed in which a color developer that develops color through interaction with microcapsules supported on a photosensitive and pressure sensitive recording medium is pulverized and can be applied electrostatically onto any medium.
しかし、製造が容易で加圧定着性能、流動性能が充分で
あり、繰り返し使用に対して現像性能、定着性能が安定
しでおり、トナー担持体、トナーケースへの癒着を起こ
さず、保存中に凝集、ケーキ化しない保存安定性の良好
である顕色剤トナーを得ることは難しかった。However, it is easy to manufacture, has sufficient pressure fixing performance and fluidity performance, and has stable development performance and fixing performance even after repeated use. It has been difficult to obtain a color developer toner that does not agglomerate or cake and has good storage stability.
顕色剤に軟質物質を含有した顕色剤トナーは、圧力定着
性は良好であるが、微粉砕してトナー化することが困難
であり、接触するトナー担持体、トナーケースへの癒着
を起こしたり保存中に顕色剤トナー同士が凝集、ケーキ
化するという開運があった。Developer toner containing a soft substance in the developer has good pressure fixability, but is difficult to pulverize into a toner and may cause adhesion to the toner carrier and toner case that it comes into contact with. As luck would have it, the developer toner would aggregate and form a cake during storage.

着される被記録媒体よりも硬いものが多く圧力を加えた
ときに、単に被記録媒体に押しつけられただけで、繊維
に絡まないためである。Further, when a hard resin is mixed with a color developer, it is easy to form a toner and has excellent chargeability and storage stability, but the pressure fixability is extremely poor. That is, the hard resin is harder than the recording medium to which it is fixed, so when pressure is applied, it is simply pressed against the recording medium and does not get tangled with the fibers.
本発明は、上述した問題点を解決するためになされたも

。The present invention has been made in order to solve the above-mentioned problems, and provides a color developer that has good fixability under pressure on plain paper, which is a recording medium, and that does not cause aggregation or caking during storage. Our objective is to provide toner products.

混合して用いるのがよい。When powdering a mixture of these color developers and electrostatically applying it to a desired medium, a dye precursor is used to improve the inability to transfer due to the fixing and charging properties of the color developer. This is done by modifying the color developer, which is the body of the color developer. What is useful at this time is to include a release material in the color developer or to cover the color developer with an outer shell containing a release material. Examples of release materials include polyfluoride. Examples include ethylene, fluororesin, fluorinated hydrocarbons, silicone oil, etc. Wax and adhesives are also used as substances that have good fixing and adhesion properties to arbitrary media and also have good adhesion to color developers. Mix the fixing agent. For example, ethylene-vinyl acetate copolymer, polyvinyl ether, vinyl chloride-vinyl acetate copolymer, polyvinyl chloride, polyacrylic acid ester, ethylene-dityl acrylate copolymer, polyvinyl acetate, which are known as adhesives. Examples include polyvinyl butyral and polyvinyl acetate. In addition, waxes include carnauba wax, candelilla 7 nox, rice wax, 7 lin wax, jojoba wax, glossy bread wax, beeswax wax, paraffin wax,
Examples include microcrystalline wax, montanic acid ester wax, halogenated paraffin wax, castor wax, Jura Nquanx, Sasolwa Nx, amide wax, osikelite, and polyolefins such as polyethylene and polypropylene. It is preferable to use these components alone or in combination so as not to lose the properties of the color developer.

If 17Il aggregation or adhesive aggregation occurs, it is also possible to apply a coating to the developer toner surface by methods such as spray drying, suspension polymerization, and emulsion polymerization. The resulting developer toner is filled into a toner case of an electrostatic developing device, charged by contact and friction between the developer and the developer carrier, and then transferred from the developer carrier onto any medium by electrostatic attraction. The image is transferred to the image recording medium and becomes useful as an image recording medium.

It is ground in a coarse grinder and then finely ground in an air jet mill. The pulverized product is very thin, ranging in size from a few microns to hundreds of microns, so in order to cut it, it is classified with an air classifier and divided into 5 to 20 microns.
A developer toner in the micron range is obtained. When this developer toner was used for development in a non-magnetic component development system, it had good fluidity (and good electrostatic transfer was performed).
