Entwicklungsvorrichtung für elektrostatsiche Ladungsbilder

摘要

In a developing apparatus, a toner stored in a vessel is supplied to a developing roller by a toner supply roller. The toner supply roller is disposed between the vessel and roller and is partitioned from vessel by a partition plate. A elastic member of the toner supply roller is brought into contact with the inner surface of the partition plate, thereby charging the toner transferred by the elastic member by friction.
