摘要： An elastic regulating member for regulating thickness of a layer of developer conveyed to a developing station by a rotatable developing sleeve is abutted against the developing sleeve. At a toner return inlet of a container associated with the developing sleeve, a flexible sheet for preventing the developer in the container from leaking through the toner return inlet is abutted against the developing sleeve along a longitudinal direction thereof. Side seals are abutted against both longitudinal end portions of the developing sleeve to prevent the developer from leaking through such longitudinal end portions. Both longitudinal end portions of the flexible sheet are overlapped with sheet supporting surfaces formed on extensions of the side seals without any clearance. Further, the both longitudinal end portions of the flexible sheet are abutted against the developing sleeve at areas outwardly of both ends of the elastic regulating member.
