A special type of ink used by copy machines and laser printers. Toner consists of a dry, powdery substance that is electrically charged so that it adheres to a drum, plate, or piece of paper charged with the opposite polarity. For most laser printers, the toner comes in a cartridge that you insert into the printer. When the cartridge is empty, you can replace it or have it refilled. Typically, you can print thousands of pages with a single cartridge.
An eraser, (also called a rubber in Canada, the UK, Ireland, India, Australia, New Zealand, and South Africa, from the material first used) is an article of stationery that is used for removing writing from paper. Erasers have a rubbery consistency and come in a variety of shapes, sizes and colours. Some pencils have an eraser on one end. Less expensive erasers are made from synthetic rubber, but more expensive or specialized erasers are vinyl, plastic, or gum-like materials.
