Abstract
A cyan toner is provided which is brighter and more greenish in hue than conventional cyan toners and highly translucency. A cyan toner characterized by comprising toner particles at least having a coloring compound represented by the Formula (1):
Claims4
A method of producing a cyan toner comprising cyan toner particles, wherein the cyan toner particles are polymer cyan toner particles produced by:
- mixing at least a polymerizable monomer, a coloring compound having a structure represented by the Formula (2):
- wherein R9 and R10 each independently represent a hydrogen atom, an alkyl group, an aryl group or an aralkyl group and a polymerization initiator to prepare a polymerizable monomer composition;
- dispersing the polymerizable monomer composition into an aqueous medium to form particles of the polymerizable monomer composition;
- and
- polymerizing the polymerizable monomer contained in the particles of the polymerizable monomer composition in the aqueous meduium.
