Abstract
A toner container used in an image forming apparatus including an exposure unit with a light emitting diode light source includes a container body, and a cyan toner stored in the container body. A lightness L*, a hue a*, and a hue b* of the cyan toner in a powder state satisfy 26.94≤L*≤34.84, −5.13≤a*≤3.83, and −47.47≤b*≤−36.78.
Claims10
A toner container used in an image forming apparatus including an exposure unit with a light emitting diode light source, the toner container comprising:
- a container body;
- and
- a cyan toner stored in the container body,
- wherein the cyan toner comprises a binder resin, Pigment Blue 15:3, and Pigment Green 7,
- wherein a content of the Pigment Blue 15:3 is greater than or equal to 5.6 parts by weight and less than or equal to 6.3 parts by weight based on 100 parts by weight of the binder resin,
- wherein a content of the Pigment Green 7 is greater than or equal to 0.5 parts by weight and less than or equal to 0.6 parts by weight based on 100 parts by weight of the binder resin, and
- wherein a lightness L*, a hue a*, and a hue b* of the cyan toner in a powder state satisfy
- 30.04≤L*≤33.68,
- −1.75≤a*≤0.71, and
