像剤とに大別することができる。(Prior art) In electrophotography, a latent image is formed on a photoconductor made of a photoconductive substance, and this is developed with a powder developer to make it visible. A two-component developer consisting of a mixture of a toner with a fluidizing agent dispersed therein and a carrier of iron powder or ferrite powder, a natural or synthetic resin, a coloring agent, a charge control agent, etc. They can be broadly classified into fluidizers and one-component developers made of magnetic materials.

に保たれる。A two-component developer achieves development by attaching charged toner to an electrostatic latent image through friction with a carrier. Conventionally, a one-component developer uses this instead of a carrier. Toner is known that is charged by friction with a brush-like or plate-like friction member that has the same function as that of the toner. It has become known that toner is charged by mutual friction with the toner. The photoconductor layer can be positively or negatively charged so that exposure under the original produces a positive or negative electrostatic latent image. Depending on the polarity of this electrostatic latent image, the developing toner remains positive or negative.

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、荷電を付与する染料、顔料さらには電荷調整
剤なるものを添加することが行なわれており、今日当該
技術分野で実用化されている。In order to keep the toner charged, it has been proposed to utilize the triboelectricity of the resin, which is the main component of the toner, but this method has a small charge on the toner and a large solid surface resistance value, so The resulting image is prone to fogging and becomes unclear. Therefore, in order to impart desired triboelectric charging properties to the toner, it has been attempted to add charge-imparting dyes, pigments, and even charge control agents, and these techniques are now in practical use in this technical field.

要条件に違背する点にある。(Problems to be Solved by the Invention) However, these dyes and pigments used as charge control agents have complex structures and lack stability, such as mechanical friction and impact, changes in temperature and humidity conditions, and electrical resistance. It is easily decomposed or altered by impact, light irradiation, etc., and the charge adjustment ability is easily lost. One essential flaw is that, being a colored material, it violates the requirement that toners with a specific hue require a charge control agent that can be considered colorless or substantially colorless. .
