Laser printing basically requires both components, toner and drum.
The image drum is the unit with which printers or photocopiers transfer the toner onto the paper. The drum is often sold in drum kits, which contain everything you need to exchange the drum. Many small laser printers now use tonercartridges that combine both the toner and the drum in a single cartridge.
At Brother, it is often necessary to replace the drum one by one.
As a wholesaler for printer accessories in northern Hamburg, Winterholt & Hering offers you a wide range of consumables and toner cartridges.
