In a developer agitating method, a developer (80) consisting of carrier and toner which are mixed by a spiral (10a) in an agitating passage (45) is agitated so that a part of the spiral is exposed out of the developer in a section, of the agitating passage, where a speed of carrying the developer is high. A developer agitating apparatus comprises an agitating passage (45), a spiral (10a) having a restricting member (W2) for reducing a performance of carrying a developer (80), a toner density sensor (30) and a toner supply mouth (60). <IMAGE> |
