PURPOSE: To supply a developer stably in the lengthwise direction of a sleeve even when numbers of copies of the same original are taken by providing a developer course changing member on a developer circulation path and then distributing the developer in the lengthwise direction of the sleeve. CONSTITUTION:A developer course changing member 6 is formed by using a bellow-shaped metallic or synthetic resin plate, etc., and making long-sized holes 61 of 6-8mm.phi therein. Its bending angle theta is determined by a developer in use. As the remaining amount of the developer becomes less, the distribution of the developer is accelerated to supply the developer uniformly in the lengthwise direction of a developing sleeve 3. |
