Abstract
An electrophotographic developer set comprising a toner, and a powder adhesive, wherein the powder adhesive comprises a crystalline polyester resin, and a thermoplastic resin other than the crystalline polyester resin; the amount of the crystalline polyester resin in the powder adhesive is 21% by mass or more; the melting point of the crystalline polyester resin is 55° C. to 100° C.; in a viscoelasticity measurement, where Gt'(100) denotes a storage elastic modulus of the toner at 100° C. and Gb′(100) denotes a storage elastic modulus of the powder adhesive at 100° C., Gb′(100) is 1.0×10Pa or less and Gt′(100)/Gb′(100) is 1.2 or more.
