<p>PROBLEM TO BE SOLVED: To prevent defective coating caused by decrease of a developer amount supplied to a developing sleeve at a downstream side of a processing chamber, in a development apparatus of a function separation type, having a regulation member that regulates a developer amount at a lower face of a developer carrier.SOLUTION: In a plurality of magnetic poles arranged inside a developing sleeve, there are a pair of magnetic poles having the same polarity and arranged adjacent to each other. In the pair of magnetic poles, a downstream magnetic pole located downstream in a rotation direction of a developer carrier is arranged at a position upstream in a rotation direction of a developer carrier with regard to the most proximate position of the developer carrier and conveyance means.</p> |
