How Does it Work?

The photocopier machine works by using the law of electrostatics and conductors. The photoconductive surface is given a postive charge. Then the surface is exposed to the image that is being copied. Due to the fact that the non-image areas becomes more conductive, the charge in the surface dissolves in the exposed areas.Following that, a negative charged powder spreads over the surface through electrostatic attraction to the positvely charged image because we know that opposite charges attract. After that, a piece of paper is placed over the powder and this gives the paper a positive charge. The negative charged powder is attracted to the positive paper as it separates from the photoconductive surface. Finally, heat fuses the powder image to the paper , producing a copy. This is how a photocopier machine works by using static electricity.

Below is a diagram of the photocopier process.
