<p>PROBLEM TO BE SOLVED: To provide a method of driving a developing apparatus, configured to periodically remove substances accumulated between a developer carrier and a regulation member, to stably form images for a long time.SOLUTION: When not in image forming operation, a developing roller 36 is driven with a supply electric field, which is weaker than in image forming operation, for moving toner from a supply roller 107 to a developing roller 36. Specifically, such as the developing roller 36 of a developing apparatus 34 is driven without applying a voltage to the developing roller 36 or applying the same voltage to the supply roller 107 and the developing roller 36 by application means 109, 110.</p> |
