- charge control agents there are many problems with these positive charge control agents.
- quaternary ammonium salt has a weak charge-imparting power! Therefore, toner images using V and V tend to cause capri and lower image density as the number of copies increases.
- triphenylmethane dye is used at high temperature and high humidity, the charge amount is lowered and the pigment in the toner is pre-filled on the surface!
- Nigguchi Shin has a high positive chargeability and is an excellent charge control agent, but its charging performance and thermal properties are greatly affected by the production method. As a result, the dispersibility of the toner for the resin was not stable, and as copying was repeated, the occurrence of capri, the decrease in image density, toner scattering, and the like were likely to cause troubles that impair print quality.
- a high acid number resin having an acid value of about 130 to 300 is modified with -glossin and added to a positively charged toner as a charge control agent.
- -Grosin modified with high acid value rosin improves dispersibility in toner grease compared to unmodified -Grosin.
- the dispersibility of the toner for the resin is still not practically satisfactory, and further improvement is desired. It was.
- Niguguchishin is a blue-black and black-colored colorant, and it reacts by heating Ahlin and -trobenzene to 160 ° C to 180 ° C in the presence of salty iron iron, iron and hydrochloric acid. To make it. A After completion of the reaction between diphosphorus and -trobenzene, neutralize by adding an alkaline aqueous solution to the reaction mixture, and separate the aniline layer. After that, it is made into a product through a base treatment with alkali, followed by washing with water, filtration, drying and grinding.
- Carryin remains in the thus-produced grosin, and usually 2,000 ppm or more of charin is detected in the gas chromatogram analysis of the dissolution method (conditions for analysis). (See the section “Best Mode for Carrying Out the Invention”).
- the residual phosphorus in the Niguchi Shin is removed by force if it is harmful when it flows out to the environment.
- glossin is used as a charge control agent for toner, the charging performance of the toner deteriorates and the fluidity of the toner This is a cause of lowering.
- Nigokushin was modified with high acid value glycerin and the conventional glycerin-modified glycine also detected more than 2,000 ppm of arsenic. There is a need to reduce it.
