The copier drum is a fundamental part of any photocopier. This part uses high-intensity light and conducts electricity as the image for a photocopy is created on the surface of the drum via static electricity. Brother Industries markets a diverse range of photocopiers for both residential and business use.
A copier drum is like a rolling stamp, with toner sticking to some parts and not to others before being applied to a page. Rather than being carved into rubber, though, the image is etched into static electricity using light. The surface of a photocopier drum is coated in selenium, a semiconducting material.
