Question

How does a photocopier use static electricity?

Answer 1

Negatively charged toner is attracted to a positively charged image

Answer 2

These negatively charged particles are attracted to the positively charged regions on the drum/belt (remember opposite charges attract). A blank sheet of paper is passed over the charged wire making it positive and then passed over the drum/belt. The positively charged paper attracts the toner off the drum/belt.Your welcome
