<P>PROBLEM TO BE SOLVED: To provide an electrophotographic toner set which provides an invisible image hardly different from an image output medium in gloss in visual observation and provides a visible image with high glossiness. Ž<P>SOLUTION: The electrophotographic toner set comprises color toner particles including a binder resin, a colorant and a release agent, and invisible toner particles including a binder resin, an near-infrared absorbing material and a release agent, wherein a weight average molecular weight MwC of the binder resin used in the color toner particles and a weight average molecular weight MwI of the binder resin used in the invisible toner particles including the near-infrared absorbing material satisfy the relationships of the expression (1): 2.0≤MwI/MwC≤4.0 and the expression (2): 8,000≤MwC≤22,000.
