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.
An imaging drum is a round rotating cylinder covered with a photosensitive surface. Images are written onto the drum by shining a focused light from the laser onto the drum. Laser printers have a drum. A primary charge roller (or in some cases a corona wire) applies between -500 and -1,000 VDC to the imaging drum. This charge neutralizes the photosensitive surface of the drum and prepares it to receive an image. A highly focused laser shines light onto the imaging drum through one or more mirrors.
