Abstract
PURPOSE:To prevent the leakage of the developer and make possible the perfect discharging of the deteriorated developer by controlling the developer passage between the spacially installed magnetic rolls for conveying developer and for forming magnetic brush by way of a freely turnable conveying member. CONSTITUTION:A predetermined amount of the developer which is uniformly stirred and mixed and is flowed down by an outflow rate control member 18 is conveyed along a non-magnetic sleeve 11 turnfing around the outside circumference of a stationary magnetic roller 10 and is pushed upward along a conveying member 9 after it has passed the conveying magnetic pole 10a. This causes the magnetic brush of the height corresponding to a shaping member 20 to be formed by the nonmagnetic sleeve 13 turning around the outside circumference of a magnetic roller 6 for forming magnetic brush intalled spacially from the roller 10, whereby a photosensitive drum 21 is subjected to development. Thence, the 2nd developing is accomplished by a similar roller 7, etc. On the other hand, if the member 9 is turned and a discharge port 3 is opened, the developer conveyed by the roller 10 is discharged, thus the leakage of the developer is perfectly prevented at the developing and the perfect discharging of the deteriorated developer may be done.
