1. An electrophotographic developer set comprising
a toner comprising a thermoplastic resin and a wax; and
a powder adhesive comprising a thermoplastic resin and a wax, wherein
where Ea (mmol/g) denotes an ester group concentration of the wax contained in the toner,
Na (mass %) denotes a content of the wax in the toner,
Eb (mmol/g) denotes an ester group concentration of the wax contained in the powder adhesive, and
Nb (mass %) denotes a content of the wax in the powder adhesive,
the Ea, the Na, the Eb and the Nb satisfy formulae:
0.00≤Ea≤2.45,
2.50≤Eb≤3.60, and
0.80≤Nb/Na.
