The photo drum in the cartridge will age, requiring a new one after some time.
Quote from the link:
The only time you need to order an empty cartridge is if your present
cartridge isn't working properly (other than just printing light due
to "toner low") or if you want to have spares on hand when your
present cartridge finally "poops out" (usually 2 - 4 refills after it
initially runs out of toner).
