| 摘要 |
A toner includes first toner particles and second toner particles. Each of the first toner particles includes a plate-like colorant particle covered with binder resin particles, and a volume average size of the plate-like colorant particle is equal to or greater than 6 μm. Each of the second toner particles includes at least one of a binder resin and a releasing agent and not including a colorant, an aspect ratio of the second toner particles is equal to or smaller than 3, and a content ratio of the releasing agents with respect to the second toner particles is equal to or greater than 4 wt % and equal to or smaller than 24 wt %. A content ratio of the second toner particles with respect to the first toner particles is greater than 1 wt % and equal to or smaller than 75 wt %. |
