Abstract

PURPOSE: To surely prevent splashing of a toner to the surroundings by providing a cover member which has an arced part concentrical with a developing sleeve and covers the developer conveyance path between a doctor and photosensitive body and a flexible sheet to the titled device.
CONSTITUTION: The doctor 10 which controls the developer to be supplied to a photosensitive body 1 side to a specified amt. is provided to face the surface of the developing sleeve 3. The cover member 16 which is formed with the arced part 16a concentrical with the sleeve 3 and covers the developer conveyance path from the doctor 10 up to the photosensitive body 1 is provided. The flexible sheet 17 which is fixed at one end to the inside surface of the cover member 16 on the doctor 10 side and is extended in a free state at the other end to the photosensitive body 1 side is provided. The splashing of the toner is thereby surely prevented with the inexpensive constitution.
