What causes the toner to transfer on the paper? Like it was negatively charged and stuck to the positive charges.

[@tearsandtunes33]

The paper, which is usually neutral or slightly positively charged, is brought into close contact with the drum. An electrically charged transfer roller or belt applies a strong positive charge to the back of the paper. The positively charged paper is attracted to the negatively charged toner particles on the drum due to their electrostatic attraction. As a result, the toner particles are pulled away from the drum and onto the paper. hope this will be enough!

[@faisalmajeed6937]

Sir I have a question why there is more production of ozone gas near the photocopiers if anyone can explain this I will be grateful

[@AllAboutPhysics]

In photocopy process corona wire us used to place electric charge to paper so toner cling on it. In this process ozone is produced

[@AllAboutPhysics]

During the process of photocopying, Ozone (O3), an unstable form of
oxygen, is the main pollutant released.

[@bismilraees4915]

Thank u soo much sir

[@sulimankhan1758]

Sir app nei charge balance ka kuch be nahi kha earth wire

[@muhammadalim9283]

How charge is neutralized?

[@niazi3463]

Jo hamari page ka contact ho ga wo dark rhay ga baqqi bright ho Jay ga iss ki waja say selenium Jo kay conducter ha wo electron provide karay ga in positive charges aor iss Tara ya positive charges neutral ho gian gay..
