Abstract
A toner set, including: a transparent toner including a binder resin a, a releasing agent a and no colorant; and one or more color toners, each including a binder resin b, a colorant b and a releasing agent b, wherein the binder resin a includes a non-crystalline resin α and a crystalline resin α, the binder resin b includes a non-crystalline resin β and a crystalline resin β, the releasing agent a has an average particle diameter as a long diameter of 0.2 μm to 2.0 μm, and there is a relationship of 1<A/B<1.5, where A is an area of the releasing agent a in a transparent toner cross-section from a surface thereof to a ⅓-depth of a volume-average particle diameter, and B is an area of the releasing agent b in a color-toner cross-section from a surface thereof to a ⅓-depth of a volume-average particle diameter.
