<P> Toner is a powder mixture used in laser printers and photocopiers to form the printed text and images on the paper , in general through a toner cartridge . Mostly granulated plastic , early mixtures only added carbon powder and iron oxide , however mixtures have since been developed containing polypropylene , fumed silica , and various minerals for triboelectrification . Toner using plant - derived plastic also exists as an alternative to petroleum plastic . Toner particles are melted by the heat of the fuser , and are thus bonded to the paper . </P>
