Abstract

In order to reduce environmental damage by toner refill cartridges constructed as disposable articles, it is proposed, in a developer station which is provided by the manufacturer with a shaft (2) to receive toner refill cartridges, to use said shaft (2) as an additional tank closed off by a lid (3), it being possible to refill said tank via a refill opening (6).
