What is the difference between a drum cartridge and a toner cartridge? For example an HP toner cartridge holds toner and dispenses it as needed to make copies (in a copier) or to prints pages (in a printer). The photoreceptor drum is the surface to which the toner adheres before being transferred to the paper. The drum has a long but finite useful lifetime and must be replaced occasionally. Some copiers/printers have drum cartridges which can be changed out by the user.
Toner is a powder used in laser printers and photocopiers to form the printed text and images on the paper, in general with a toner cartridge. In its early form it was a mix of carbon powder and iron oxide. Then, to improve the quality of the printout, the carbon was melt-mixed with a polymer. Toner particles are melted by the heat of the fuser, and are thus bonded to the paper. In earlier machines, this low-cost carbon toner was poured by the user from a bottle into a reservoir in the machine.
