• How does a photocopier work static electricity? The drum is selectively charged with static electricity to mirror the image that is being copied. The toner, which is black powder, then adheres to the charged areas of the drum. Finally, a blank piece of paper is charged with static electricity.

Video answer: Electric charge - how a photocopier works

How does a photocopier work static electricity? The drum is selectively charged with static electricity to mirror the image that is being copied. The toner, which is black powder, then adheres to the charged areas of the drum. Finally, a blank piece of paper is charged with static electricity.

There are multiple components inside of a photocopier, including a drum and toner. The drum is selectively charged with static electricity to mirror the image that is being copied. The toner, which...

A photocopier uses static electricity by positively charging the ink and negatively charging the paper so that the positively charged ink can uniformly print on the paper.

How does a photocopier use static electricity? To make a new copy, the paper that you are copying is placed downwards onto a sheet of glass. Using static electricity, an image of this paper is projected onto a positively charged drum. The coating on the drum can conduct electricity when light hits it.

Photo: Look, no hands! Static electricity can "glue" things together using opposite electrical charges. This science is put to practical use inside a photocopier. How does this happen? As you rub the balloon, electrons (the tiny negatively charged particles inside atoms that carry electricity) move from your pullover onto the balloon.

The way this selectivity is accomplished in a copier is with light-- this is why it's called a photocopier! Somehow the toner has to get onto the drum and then onto a sheet of paper. The drum selectively attracts toner. Then the sheet of paper gets charged with static electricity and it pulls the toner off the drum.
