Abstract
Official abstract text for this publication.
Provided is a toner containing a toner particle including a binder resin, a wax, and a colorant. The softening point of the toner is at least 80° C. and not more than 140° C. The average circularity of the toner is at least 0.940. The integrated value of stress in the toner at 150° C. which is measured by using a tackiness tester is at least 78 g·m/sec.
First claim
Opening claim text (preview).
What is claimed is: 1. A toner comprising a toner particle including a binder resin, a wax, and a colorant, wherein the wax comprises an ester wax, the ester wax being (i) an ester compound of a dihydric alcohol and an aliphatic monocarboxylic acid, or (ii) an ester compound of a divalent carboxylic acid and an aliphatic monoalcohol, a softening point of the toner is 80 to 140° C.; an average circularity of the toner is at least 0.940; and an integrated value of stress in the toner at 150° C. is at least 80 g·m/sec when measured using a tackiness tester on a toner pellet obtained by compressing the toner. 2. The toner according to claim 1 , wherein the binder resin is a styrene-acrylic resin. 3. The toner according to claim 1 , wherein the colorant is a magnetic body. 4. The toner according to claim 1 , wherein a thermal conductivity of the toner is 0.190 to 0.300 W/mK. 5. The toner according to claim 1 , wherein the average circularity of the toner is at least 0.950. 6. The toner according to claim 1 , wherein the integrated value of stress in the toner at 150° C. is 80 g·m/sec to 130 g·m/sec. 7. The toner according to claim 1 , wherein the wax consists of the ester wax.
