AI overview
A photocopier is a machine that quickly and inexpensively makes copies of documents and images onto paper or plastic film using a technology called xerography, which applies powdered toner to paper through electrostatic charges and heat. Photocopiers matter because they enable rapid, affordable document reproduction, making them essential for offices, schools, and other institutions that need to duplicate written and visual materials.

The toner is then fused onto the paper using heat, pressure, or a combination of both. Copiers can also use other technologies, such as inkjet, but xerography is standard for office copying.
Commercial xerographic office photocopying gradually replaced copies made by verifax, photostat, carbon paper, mimeograph machines, and other duplicating machines.
