Abstract
PURPOSE: To perform always stable coating of developer and make possible stable and good-quality development by providing a removing means of removing the developer on the surface of a developer holding means during the feeding process of the developer and again imparting the same to the holding means and a magnetic capturing means in the position downstream thereof.
CONSTITUTION: A developer removing plate 6 composed of phosphor bronze or the like is mounted in the counter direction to the moving direction of the developer layer and the scraping off of the developer is once performed for the developing sleeve surface during the process of feeding the developer from a hopper 5. Multiple holes are provided near the portions of this removing plate 6 in contact with the sleeve. Further, a magnetic capturing member 8 composed of magnetic body for capturing the lumps of the developer is provided in the position behind the removing plate 6. Thereby, not only the cohered developer and fused developer but also magnetic foreign material and particularly magnetic developer of much magnetic powder content may be captured by the capturing member 8. This makes it possible to perform stable and good-quality development.
