Answers below are taken from the article’s stored facts, so they match what the student read.

1. How big is Toner?Typically 5-15 micrometers, with chemically produced toners offering greater uniformity
2. What is the manufacturing processes?Includes mechanical grinding and advanced chemical methods like Emulsion Aggregation (EA)
3. What is toner and why does it look like magic in a printer?Toner is a special powder made of tiny plastic particles with color that sticks to paper when a printer heats it, creating sharp pictures and words.
4. How does a laser printer use toner to make a picture?The printer charges a drum, a laser writes the picture, toner sticks to the charged spots, then the paper pulls the toner and heat melts it onto the paper.

Electrophotography: A process using light and electrostatic charges to create images, fundamental to laser printing.
Triboelectric Effect: The charging of materials through contact and separation, crucial for toner particle charging.
Emulsion Aggregation (EA) Toner: Chemically produced toner with uniform particle size and shape, offering superior print quality and efficiency.
