の無色または淡色の荷電制御剤の要望が大きい。The developing powder used in these developing methods is a fine powder in which a dye or a pigment is dispersed in a thermoplastic resin, and a developing powder in which a third substance as described in JP-B-44-6398 is added. Is also known. However, since the above-mentioned developing powder alone does not have a preferable charging property, a dye or a pigment which imparts charging property is added, and it is considered to be practically used at present when a negative charge is given to a toner. The metal-containing dye is a nigrosine-based dye when a positive charge is given. Although these dyes are charge control agents having excellent properties, they cannot be used in color electrophotography which has been particularly strongly demanded in recent years because they are colored substances. Therefore, there is a great demand for colorless or light-colored charge control agents for minus toners which are mainly used at present.
そこで、本発明者は、無色または淡色で良好な現像特性
