Abstract
A toner container used in an image forming apparatus including an exposure unit with a light emitting diode light source. The toner container including a container body, and a cyan toner stored in the container body. The cyan toner includes a binder resin, at least one pigment, a charge control agent, and an external additive. The at least one pigment includes at least Pigment Blue. 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 −47.47≤b*≤−45.08.
