How does the photocopier work?
In a photocopier, the light-induced conductivity of the drum is exploited to create a latent image in the form of electrical charges on the surface of the drum. This image is made visible and transferred to paper using a special, charged toner.
How do photocopiers work step by step?
A piece of paper is placed over the powder image and then given a positive charge. The negatively charged powder is attracted to the paper as it is separated from the photoconductor. Finally, heat fuses the powder image to the paper, producing a copy of the original image.
How do photocopiers work for kids?
But how do they work? The bright light you see moving across the image in a photocopier charges the plain paper with electricity – a bit like when you rub a balloon and it makes your hair stick up. The charge is in the exact pattern of the words or pictures on your original.
How does a photocopier work Wikipedia?
Most modern photocopiers use a technology called xerography, a dry process that uses electrostatic charges on a light-sensitive photoreceptor to first attract and then transfer toner particles (a powder) onto paper in the form of an image.

How a photocopier uses static electricity?
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.
