Abstract
Official abstract text for this publication.
Provided is a toner that uses a crystalline resin, and demonstrates favorable dispersibility of the crystalline resin in the toner, demonstrates superior low-temperature fixability, and is able to inhibit fogging. The toner has a toner particle comprising a resin A, which has a long-chain alkyl group having an average number of carbon atoms of 27 to 50, and a crystalline resin, wherein the SP value (cal/cm 3 ) 1/2 of the crystalline resin is 9.00 to 12.00, and in a GC/MS analysis of components that volatize when the toner is heated for 10 minutes at 200° C., the amount of volatile components of saturated hydrocarbons having 30 to 37 carbon atoms is 90 ppm to 260 ppm of toluene equivalent, based on mass.
First claim
Opening claim text (preview).
What is claimed is: 1. A toner having a toner particle comprising a resin A, which has a long-chain alkyl group having an average number of carbon atoms of 27 to 50, and a crystalline resin, wherein the SP value (cal/cm 3 ) 1/2 of the crystalline resin is 9.00 to 12.00, in a GC/MS analysis of components that volatize when the toner is heated for 10 minutes at 200° C., an amount of volatile components of saturated hydrocarbons having 30 to 37 carbon atoms is 90 ppm to 260 ppm of toluene equivalent, based on mass, and the resin A is a hybrid resin in which a polyester segment and a vinyl-based polymer segment are chemically bonded and a mass ratio of the polyester segment to the vinyl-based polymer segment (polyester segment/vinyl-based polymer segment) in the resin A is 50/50 to 90/10. 2. The toner according to claim 1 , wherein the peak temperature of the maximum endothermic peak of the crystalline resin as measured by differential scanning calorimetric measurement is 50.0° C. to 100.0° C.
