像濃度の低下を発生するという問題があった。Problems to be Solved by the Invention However, since dyes themselves are colored, they cannot be used in color toners with different tones, and since many amine salt compounds are water-soluble, they cannot be sufficiently charged. In order to obtain the desired amount, it is necessary to increase the amount added, and even in that case, there is a problem that the amount of charge is unstable due to the influence of humidity. Furthermore, 1ζ amino group-containing resin has a problem in terms of heat resistance, and during the toner manufacturing process, it thermally decomposes when kneaded with thermoplastic resin, resulting in variations in the amount of charge for each toner particle, and as a result, toner scattering during continuous copying. There have been problems with fogging and a decrease in image density.
本発明は、」二記問題点に鑑み、帯電量の立ち」二りが
