Photosensitive material refers to a semiconductor material that has photosensitivity characteristics, and is therefore also referred to as a photoconductive material or a photosensitive semiconductor. Photosensitive materials commonly used in photocopiers include: organic photosensitive drums (OPC), amorphous silicon photosensitive drums, cadmium sulfide photosensitive drums, and selenium photosensitive drums.
Its characteristic is that it is insulative in the absence of light and conductive in the state of light. The working principle of the copy machine is to take advantage of this feature. In a copying machine, a photosensitive material is applied on a substrate to make a printing plate (printing drum) to be used for copying, so the printing plate is also referred to as a photosensitive plate (photosensitive drum), and the photosensitive plate is a copying machine. The basic core components. The commonly used photosensitive materials on photocopiers include selenium, zinc oxide, cadmium sulfide, and organic photoconductors, which are ideal photoconductive materials.
