摘要： A toner including a colorant, a polyester (I), and an urea-modified polyester is provided. The urea-modified polyester is a reaction product of an isocyanate-modified polyester with an amine. The isocyanate-modified polyester is obtained by modifying a polyester (II) with an isocyanate. The polyester (II) has specific number average molecular weight (Mn) and hydroxyl value [OHV]. The toner can be manufactured by dispersing or emulsifying a toner constituent liquid including the colorant, the polyester (I), and the isocyanate-modified polyester, in an aqueous medium. The toner can be used for a one-component developing device.
