Explanation:
Detailed explanation-1: -During the laser printer process, after the erase lamp exposes the entire surface of the photosensitive drum to light, what happens to the photosensitive coating? It becomes conductive. What does the primary corona wire charge? The toner in a laser printer is a fine powder.
Detailed explanation-2: -The laser creates an image of the page on the drum in the writing stage. An electrostatic charge is applied to the paper to attract toner in the transferring stage, which happens immediately after the developing stage.
Detailed explanation-3: -Electrophotography involves the removal of negative charges by the use of light from the surface of a photosensitive cylinder, which is then covered with the toner.
