DRY TONERS

摘要

(1) A dry toner which is excellent in powder flowability and transferability when having a reduced toner particle diameter; (2) a dry toner which is excellent in all of high-temperature storage stability, low-temperature fixability, and high-temperature non-offset properties; (3) a dry toner which, when used in a full-color copier, etc., gives an image excellent in gloss; and (4) a dry toner which does not necessitate the application of an oil to the heated roll. The toners each comprises a toner binder and a colorant and has a Wadell's practical sphericity of 0.90 to 1.00. The toner binder comprises a high-molecular condensation resin (A) and a low-molecular condensation resin (B), wherein the ratio of the number-average molecular weight of the resin (A) to that of the resin (B), (MnA/MnB), is 1.6 or higher and the ratio of the weight-average molecular weight of the resin (A) to that of the resin (B), (MwA/MwB), is 2 or higher.
