- A selenium coated drum is rubbed onto a brush. The selenium coated drum is positively charged.
- The light is shined onto the page that is to be copied. Being reflected through several mirrors, it is finally reflected onto the selenium coated drum.
- The selenium becomes conductive as the light hits it. The charges get rearranged until the charge is neutral. There is only positive charge on the parts of the drum where there was no light- the silhouette of the print on the page being photocopied.
- There is a brush that picks up negatively charged toner (a fine black powder) made of plastic beads and carbon particles. When the brush rolls onto the selenium, the negative toner is attracted to the positive charge left on the drum.
- Positively charged paper picks up the toner from underneath the selenium coated drum.
- The paper is finally heated to melt and seal the toner onto the paper.

How do photocopiers make use of static-electric forces?
Photocopiers use static electric forces to attract toner particles to the charged drum surface. The charged drum transfers the toner onto the paper, creating a copy of the original image. This process is enabled by the static electricity's ability to create a strong attraction between the charged drum and the toner particles.
What are 2 uses of static electricity?
Static electricity is used in photocopiers and laser printers to attract toner particles to the paper. It is also used in industrial applications to remove dust and unwanted particles from surfaces through static charge.
What devices use static electric charges?
Devices such as photocopiers, printers, and air purifiers use static electric charges to attract and transfer toner particles onto paper, generate static electricity to separate particles from the air, and transfer particles to collection plates respectively. They create static charges by friction or induction to perform their functions effectively.
What does a static electric ball do?
A static electric ball creates static electricity which can attract and repel objects when touched. It can be used for educational demonstrations or for simple entertainment purposes.
What are some things that use static electricity to function?
Some common things that use static electricity to function include photocopiers, printers, air purifiers, and paint sprayers. Static electricity is used in these devices to attract particles, create a static charge for imaging, or facilitate the transfer of paint particles.
Where can one sell used photocopiers that still work online?
There are many places where one can sell used photocopiers that still work online. There are companies, such as "brkassociates" and "copexinc", that will buy used photocopiers.
Why static electricity don't have electric charge?
Static electricity DOES have an electric charge.
What is Stationary electric charge called?
A stationary electric charge is called an electric static charge.
What are the various practical applications and uses of static electricity?
Static electricity has various practical applications, including in industries like printing, painting, and dust removal. It is also used in air filters, photocopiers, and xerography machines. Additionally, static electricity is utilized in technologies like inkjet printers, electrostatic precipitators, and electrostatic painting.
When can a static electric field arise?
A static electric field can arise when there is a buildup of electric charge in a stationary object or material.
