Abstract
A toner usable with electrophotography includes an iron (Fe) content in the toner is in a range of about 1.0×102 ppm to about 1.0×104 ppm and a circle equivalent diameter of a sectional area of an Fe agglomerating agent is in a range of about 1.0 nm to about 2.0×102 nm.
Claims15
A toner usable with electrophotography, comprising:
- a latex;
- a colorant;
- and
- a release agent,
- wherein an iron (Fe) content in the toner is in a range of about 1.0×102 ppm to about 1.0×104 ppm and a circle equivalent diameter of a sectional area of an Fe agglomerating agent is in a range of about 1.0 nm to about 2.0×102 nm.

A method of preparing a toner usable with electrophotography, the method comprising:
- preparing a mixture solution by mixing first latex particles with a colorant dispersion and a release agent dispersion;
- preparing a first agglomerated toner by adding an agglomerating agent to the first latex particles;
- and
- preparing a second agglomerated toner by coating second latex particles on the first agglomerated toner prepared by polymerizing at least one polymerizable monomer,
- wherein an iron (Fe) content in the toner is in a range of about 1.0×102 ppm to about 1.0×104 ppm and a circle equivalent diameter of a sectional area of an Fe agglomerating agent is in a range of about 1.02 nm to about 2.0×102 nm.
