Abstract:
A toner comprising an amorphous polyester, a crystalline polyester that is forming domains in the toner, and a colorant that is being dispersed at least in the domains of the crystalline polyester. The toner may be obtained by dispersing an oil phase including the amorphous polyester or a precursor capable of producing the amorphous polyester, the crystalline polyester, the colorant, and an organic solvent, in an aqueous medium to prepare an O/W dispersion, the oil phase; and removing the organic solvent from the O/W dispersion.
