Patent ID: 8007977

Claim:
A toner, comprising: binder resins, including a crystalline polyester resin and an amorphous polyester resin; and a colorant; wherein: the toner is prepared by a method, comprising: dissolving or dispersing at least the binder resins and the colorant in a solvent to prepare a toner constituent liquid; emulsifying or dispersing the toner constituent liquid in an aqueous medium comprising a particulate resin to granulate; and removing the solvent; the toner comprises from 1 to 30% by weight of the crystalline polyester resin based on a total weight of the binder resins; the toner has a circularity of from 0.97 to 0.995; and the toner satisfies the following relationships: 40° C.< T 1<80° C.; and 10° C.<( T 1- T 2) <47.9° C.; wherein T 1 represents a glass transition temperature of the toner before melting when heated from −20° C. to 150° C. at a heating speed of 10° C./min, and T 2 represents a glass transition temperature of the toner after melting after being heated from −20° C. to 150° C. at a heating speed of 10° C./min, cooled to −20° C. at a cooling speed of 10° C./min and heated again at a heating speed of 10° C./min.
