<P>PROBLEM TO BE SOLVED: To provide toner having favorable low-temperature fixability and high-temperature-resistant offset property with no fixing irregularity without affecting a long-term storage stability. <P>SOLUTION: The toner includes toner particles formed by suspending, in an aqueous medium, a toner material that is formed by dissolving and/or dispersing at least a binder resin and a colorant in an organic solvent, forming oil droplets, and then removing the organic solvent therefrom. The binder resin includes at least a polyester resin, and the polyester resin has a first endothermic peak P1 at a temperature of 55 to 75°C and a second endothermic peak P2 at a temperature of 80 to 120°C in a DSC curve measured by a differential scanning calorimeter. <P>COPYRIGHT: (C)2013,JPO&INPIT |
