Title
(EN) TONER FOR ELECTROSTATIC CHARGE IMAGE DEVELOPING
(FR) TONER POUR DÉVELOPPEMENT D’IMAGE À CHARGE ÉLECTROSTATIQUE
(JA) 静電荷像現像用トナー
Abstract
(EN)
Provided is a toner for electrostatic charge image developing, with which toner blow-off is unlikely to occur and which has excellent printing durability. This toner for electrostatic charge image developing contains: coloring resin particles, which comprise a binder resin, a coloring agent and a charge control agent; and external additives. The toner is characterized in that: the toner contains, as the external additives, at least an external additive A and an external additive B; the external additive A is silica particles which have a specified number average particle diameter and the surface of which is subjected to a hydrophobic treatment using a specified hydrophobic treatment agent; the external additive B is silicone resin particles which have a specified number average particle diameter and for which the ratio (BS/TS) of the BET specific surface area (BS) relative to the theoretical specific surface area (TS) falls within the range 3.0-30.0; and the content of external additive A and that of external additive B fall within specified ranges relative to the binder resin particles.

L’invention fournit un toner pour développement d’image à charge électrostatique présentant peu de risques de soufflage de toner, et doté d’une excellente durabilité d’impression. Plus précisément, l’invention concerne un toner pour développement d’image à charge électrostatique qui comprend des particules de résine de coloration contenant une résine de liaison, un agent de coloration ainsi qu'un agent inhibiteur d’électrification, et un additif externe. Ce toner pour développement d’image à charge électrostatique est caractéristique en ce qu’il comprend au moins un additif externe (A) et un additif externe (B) en tant qu’additif externe. Ledit additif externe (A) consiste en des particules de silice dotées d’un diamètre particulaire en nombre spécifique dont la surface est soumise à un traitement hydrophobe par un agent de traitement hydrophobe spécifique. Ledit additif externe (B) consiste en des particules de résine de silicone dotées d’un diamètre particulaire en nombre spécifique dont le rapport (BS/TS) d’une surface spécifique BET (BS) par rapport à une surface spécifique théorique (TS), est compris dans une plage de 3,0 à 30,0. Enfin, ledit additif externe (A) et ledit additif externe (B) sont compris dans le toner en quantité spécifique par rapport auxdites particules de résine de coloration.
