Abstract

PURPOSE: To remove a developer attached to a developing sleeve and carried in the direction reverse to that of developer transportation from the sleeve surface, by providing a cleaner blade and a developer scraping blade in pressure contact to the sleeve surface.
CONSTITUTION: Developing sleeve 2 rotating in the direction reverse to that of developer carrying and magnetic roller 3 rotating at high speed in the direction same as that of sleeve 2 are installed in a developing unit. Cleaner blade 8a is provided in pressure contact to the sleeve 2 surface for removing the developer carried in the direction reverse to that of developer carrying, and developer scraping blade 8b is installed for removing the used developer from the sleeve surface, but allowing passage of the developer attached to sleeve 2 and carried in the direction reverse to that of developer carrying.
