Abstract
Provided are methods of electrophotographically printing an image on a substrate, methods of transferring an image to a substrate, electrophotographic toner cartridge kits, and electrophotographic printing devices. A plurality of layers of toner particles may be electrophotographically printed, using toner cartridges, providing an imaged area that includes one or more colorant layers that include a colorant and a colorant-layer thermoplastic adhesive, and an adhesive layer that includes an adhesive-layer thermoplastic adhesive. The fusing temperature may be selected to heat the colorant-layer thermoplastic adhesive to a temperature greater than an activation temperature of the colorant-layer thermoplastic adhesive and/or an activation temperature of the adhesive-layer thermoplastic adhesive. The melting temperature, the fusing temperature, or melt flow rate of the colorant-layer thermoplastic adhesive corresponding to at least one of the one or more colorant layers may exceed the melting temperature, the fusing temperature, or the melt flow rate of the adhesive-layer thermoplastic adhesive.
