PROBLEM TO BE SOLVED: To provide a foil transfer device that can increase the adhesive strength between a metal foil and a first toner image.SOLUTION: An image forming apparatus 1 comprises: a first image forming part 6 that transfers a first toner onto a sheet to form a first toner image; and a foil transfer part 100 that transfers a metal foil to the first toner image. The first toner is made to contain a binder resin and an adhesive. The adhesive is made to contain a copolymer of a functional group-containing vinyl monomer containing a tertiary amino group or a quaternary ammonium salt and a vinyl monomer copolymerizable with the functional group-containing vinyl monomer. When the functional group-containing vinyl monomer contains the quaternary ammonium salt, the content ratio of the quaternary ammonium salt in the adhesive to the first toner is made 0.28 mass% or more and 20.0 mass% or less. When the functional group-containing vinyl monomer contains the tertiary amino group, the content ratio of the tertiary amino group in the adhesive to the first toner is made 2.65 mass% or more and 20.0 mass% or less.SELECTED DRAWING: Figure 1
