Genuine OEM Canon imageRUNNER Advance 4025 Toners

The imageRUNNER Advance 4025 uses GPR-43 black toner and a separate GPR-42/43 drum. The two numbers in the drum's name do not make it a toner choice: it is a different supply, and ordering a drum does not add toner.

Toner Buzz carries genuine Canon GPR-43 black toner and the GPR-42/43 drum for the 4025. Choose GPR-43 when you need toner, or the GPR-42/43 drum when that separate unit needs attention. Both are black supplies, but they are not interchangeable.
