Question

What is that black powder used in xerox machie?

Answer 1

Black powder or toner is mostly granulated plastic, early mixtures only added carbonpowder and iron oxide, however mixtures have since been developed containing polypropylene, fumed silica, and various minerals for triboelectrification.[1] Toner using plant-derived plastic also exists as an alternative to petroleum plastic.[2] Toner particles are melted by the heat of the fuser, and are thus bonded to the paper.
