(57) [Summary] (Modified) [Constitution] In a toner containing a colorant and a binder resin as main components, the binder resin component is obtained by end-capping the epoxy groups at both ends of the epoxy resin. ) ~ (4) At least one softening point 100-115 selected from Containing a polyol resin at 0 ° C. (1) A reaction product (2) obtained by reacting a monovalent active hydrogen-containing compound with an epoxy group at both ends, and further a reaction product obtained by esterifying a secondary hydroxyl group (3) Both-end epoxy group The reaction product (4) (3) obtained by reacting a primary amine with a dihydric phenol, and further reacting with a monovalent active hydrogen-containing compound, to esterify the secondary hydroxyl group. [Effect] The charge is stable to the positive polarity, the color reproducibility is good, the image is glossy, the image surface does not curl, it is chemically and biochemically stable, safe and environmentally stable, and the dye and pigment are well dispersed. , No transfer to PVC mat. |
