The main function of a photocopier is to produce paper copies of a document. Most photocopiers use laser technology, a dry process that uses electrostatic charges on a light-sensitive photoreceptor to transfer toner onto paper to form an image.

How do photocopiers use static electricity?

For a photocopier to work, a field of positive charges must be generated on the surface of both the drum and the copy paper. These tasks are accomplished by the corona wires. These wires are subjected to a high voltage, which they subsequently transfer to the drum and paper in the form of static electricity.
