Developing device

Abstract

Abstract PURPOSE:To separate the residual developer from a developing roll and to convey it continuously without overflowing out of a developing device by providing a conveyance assisting member which returns a developer scraped with a developer separating member onto a developer holding member and a developer fall preventing member. CONSTITUTION:The developing device 20 is provided with two conveyance assisting members, i.e. 21 and 22. The developer scraped off the developing roll 11 with a scraper 16 is sprung up with the conveyance assisting member 21 and sent toward the developing roll 11 with the conveyance assisting member 22 beyond the scraper 16. Two functions of preventing the banking of a developer and of sticking the developer to the developing roll 11 are separated, and the different conveyance assisting members 21 and 22 take charge of a portion of them respectively. The developer is supplied invariably stably without scattering from the opening part 12A under a hopper 12 nor being overflowed from the developing roll 11.
