发明名称 Toner containing crystalline polyester
摘要 A toner including a binder resin which contains a crystalline polyester resin and a non-crystalline polyester resin, wherein the crystalline polyester resin has at least two diffraction peaks in a range of 20°<2θ<25° as detected by X-ray diffraction measurement, and has a melting point which is 60° C. or higher but lower than 80° C., and wherein the diffraction peaks each have a half width which is less than 1.0°.

主权项 1. A toner comprising: a binder resin which contains a crystalline polyester resin and a non-crystalline polyester resin, and an amine elongation composition of polyester modified with an isocyanate, wherein the crystalline polyester resin is obtained by synthesizing with: at least one alcohol component selected from the group consisting of ethylene glycol, 1,4-butanediol, 1,6-hexanediol, 1,8-octanediol, 1,10-decanediol, and 1,12-dodecanediol, andat least one dicarboxylic acid component selected from the group consisting of 1,10-decanediacid and 1,12-dodecanediacid; wherein the crystalline polyester resin has at least two diffraction peaks in a range of 20°<2θ<25° as detected by X-ray diffraction measurement, and has a melting point which is 60° C. or higher but lower than 80° C.; and wherein the diffraction peaks each have a half width which is less than 1.0°.
