摘要： A positively charging dry toner for developing an electrostatic latent image including a nigrosine dye or nigrosine pigment containing 500 ppm or less nitrobenzene and 800 ppm or less aniline as a charge controlling agent. The dye or pigment is prepared by dispersing the nigrosine dye or nigrosine pigment obtained by an usual method in a solvent, adding an oxidizing agent such as bleaching powder to the solvent dispersion to conduct oxidation treatment and, if necessary, removing the solvent by steam distillation.

摘要： A toner for developing an electrostatic latent image is disclosed, which contains as a charge control agent a trivalent chromium salt of salicylic acid or a derivative thereof represented by the following general formula;
wherein
R 1 , R 2 and R 3 each represents a hydrogen atom, a saturated or unsaturated, straight or branched alkyl group or, when taken together, R 1 and R 2 or R 2 and R 3 form a fused ring optionally having a saturated or unsaturated, straight or branched alkyl group, and n represents 0, 1 or 2. The trivalent chromium salts are formed by adding an aqueous solution of alkali metal salt of salicylic acid or a derivative thereof having a pH of 6.5 to less than 7.0 to an aqueous solution of a chromium (III) halide having a pH of 3.0 to 5.8.摘要翻译： 公开了一种用于显影静电潜像的调色剂，其包含作为电荷控制剂的由以下通式表示的水杨酸的三价铬盐或其衍生物; 其中R 1，R 2和R 3各自表示氢原子，饱和或不饱和的直链或支链烷基，或者当R 1和R 2或 R 2和R 3形成任选具有饱和或不饱和的直链或支链烷基的稠环，n表示0,1或2.三价铬盐是通过加入碱金属盐水溶液 的水杨酸或其pH为6.5至小于7.0的衍生物与pH为3.0至5.8的卤化铬（III）的水溶液混合。
