What is the primary substance used in laser printers for creating images on paper?

• A. Ink
• B. Paper
• C. Toner
• D. Color pigments

Answer: (C)

The primary substance used in laser printers for creating images on paper is toner. Toner is a fine powder made of plastic particles, carbon, and coloring agents that is essential to the laser printing process. When a laser printer processes a document, it uses a laser beam to create an electrostatic image on a drum. The toner is then attracted to this charged image and is transferred onto the paper, where it is fused using heat to create a permanent image. This technology distinguishes itself from inkjet printers, which utilize liquid ink to produce images. While other options may pertain to different printing technologies or components, toner specifically aligns with the operational mechanics of laser printers. Toner allows for high-quality images and text due to its consistent density and the ability to produce fine details, which is crucial in a variety of printing applications.
