Abstract
PURPOSE: To convey magnetic developer in a good state by using magnetic rollers and guide members with scrapers.
CONSTITUTION: A case 15 containing magnetic rollers 13, 14 disposed below an elastic cleaning blade 12 which is in contact with a photosensitive drum 11. Guide members 16, 161 with scrapers 171, 172 of V-form are provided above the magnetic roller 14 to form a developer well 18. As a result of this, the magnetic developer T scraped off from the photosensitive drum 11 surface by the elastic cleaning blades 12 is attracted to the magnetic roller 13 and is moved as the roller revolves. It is then force fed upward while being held by the restraining magnetic field generated between said roller and the magnetic roller 14 as a counter magnetic pole. While it is being scraped off by the scrapers 171, 172, it is conveyed into the developer well 18 without causing solidification and modification and without being flown.
