Original Canon drum fro C-EXV 16 and C-EXV 17 toners.
In order to use your toner it must be sat into a drum and then both inserted into the printer as one unit.
It's actually the drum that does all the "work" while the toner is simply a container of coloured powder.
This drum lasts for 60,000 pages and is replaced separately from the associated toners.
Please note this is a DRUM and not a toner.
The Canon C-EXV 17 toner magenta ensures a good colour print. With this toner, images and graphs come into their own. This is because the prints are printed sharp and detailed on paper.
