PROBLEM TO BE SOLVED: To provide an electrophotographic toner set which can form a an invisible image with nearly the same glossiness to that of image output medium when being viewed and can form a visible image with high glossiness. SOLUTION: This electrophotographic toner set consists of color toner particles containing a binder resin, coloring agents, and an mold releasing agent and invisible toner particles containing a binder resin, near-infrared light absorption materials, and a mold releasing agent. The gel fraction of the above binder resin used in the above invisible toner particles is 15 wt.% or more but 45 wt.% or less. The gel fraction GI of the binder resin used in the above invisible toner particles and the gel fraction GC of the binder resin used in the above color toner particles satisfy the following formulas: formula (1):ΔG=äGI-GC}; and formula (2): 10 wt.%≤ΔG≤45 wt.%.
