Title (EN) TONER
(FR) TONER
Abstract: front page image
(EN)A toner, including: a colorant; a binder resin; and a releasing agent, wherein the binder resin includes a polyester resin, and the toner satisfies requirements (1) and (2) below: (1): G'(50) ≥ 3.0 x 107Pa and 1.0 x 105 Pa ≤ G'(60) ≤ 1.0 x 107 Pa, where G'(50) is a storage modulus at 50°C of the toner and G'(60) is a storage modulus at 60°C of the toner; and (2): a spin-spin relaxation time of the toner at 50°C measured by solid echo method of pulse NMR is 1.0 ms or shorter.
(FR)L'invention concerne un toner, comprenant : un colorant ; une résine employée comme liant ; et un agent de libération, la résine employée comme liant comprenant une résine polyester, et le toner satisfaisant les exigences (1) et (2) ci-dessous : (1) : G'(50) ≥ 3.0 x 107Pa et 1.0 x 105 Pa ≤ G'(60) ≤ 1.0 x 107 Pa, où G'(50) est un module de conservation à 50°C du toner et G'(60) est un module de conservation à 60°C du toner ; et (2) : un temps de relaxation spin-spin du toner à 50°C mesuré par un procédé d'écho solide d'une impulsion NMR est de 1,0 ms ou plus court.
