Abstract: In the present invention, an image forming apparatus using a method of replacing a developer is configured such that an immobile area in which the heights of a discharge passage and a conveyance passage are changed on the upstream side of a returning screw is filled. This causes the immobile area of the developer to be unlikely to occur and accordingly suppresses formation of a toner stain image due to an aggregation toner, enabling stable image formation over a long period of time.
