Claims

[Scope of utility model registration request]

(1) In a two-component developing device in which a two-component developer consisting of carrier and toner is stored in a developer storage section, and magnetic brush development is performed using the developer stored in the developer storage section, the toner is a toner replenishing means for replenishing; a receiver for temporarily receiving toner from the toner replenishing means and developer recovered after magnetic brush development; a stirring means provided on the member; A loop U for supplying the toner and the recovered developer to the developer storage section after stirring the toner and the recovered developer using a stirring means.
1. A two-component developing device comprising a control means.

(2) The receiving member is disposed below the toner replenishing means, at a collection position from the means forming the magnetic brush, and above the developer storage section, and is approximately semi-tubular in shape with an opening. The control means is arranged such that it extends horizontally and can be angularly displaced, and the control means directs the opening of the receiving member upward when stirring the toner and recovered developer, and directs the opening downward when supplying the developer to the developer storage section after stirring. A two-component developing device according to claim 1, wherein the receiver angularly displaces the member so as to direct the member.
