Explanation:
Detailed explanation-1: -Printer toner is a very fine powder composed mainly of plastic polymer and coloring agents. Toner powder is electrostatically charged inside the printer and fused to the paper as it passes over a metal drum in the printer. Black toner is typically used in laser printing.
Detailed explanation-2: -Black laser toners contain carbon black powder combined with powdered plastic. What else is in there? Fumed silica, which keeps the powdered toner particles loose and flowing freely inside the cartridge, and charge control agents-powdered iron, chromium and zinc-which maintain the charge of the particles.
