What does toner used in laser printers contain?

Toner used in laser printers typically contains a mixture of fine plastic particles, carbon black for pigment, and various additives to improve flow and adherence. The plastic particles are usually made from styrene-acrylate or similar polymers that melt when heated to fuse the toner onto the paper. The carbon black provides the black color, while additives can enhance properties like charge control and fluidity. This combination allows for high-quality printing with sharp text and images.
