Abstract
PURPOSE: To perform always stable coating of developer and make possible stable and good-quality development by providng a removing means of removing the developer on the surface of a developer holding means prior to feeding of the developer and again imparting the same to the holding means surface and a mangetic capturing means in the position downstream thereof.
CONSTITUTION: A developer removing plate 6 composed of phosphor bronze or the like is mounted in the upstream position in the moving direction of the developer layer to the developing sleeve surface and the scraping off of the developer by the same is once performed prior to feeding of 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 9 composed of magnetic body for capturing the lumps of the developer is provided between the removing plate 6 and hopper 5. 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 9. This makes it possible to perform stable and good-quality development.
