PURPOSE:To facilitate handling to prevent flowing-away of a toner due to erroneous operations and to supply the toner uniformly to the overall area of a photosensitive drum, by closing respective aperture parts, which can coincide with each other, of an inside cylinder and an outside cylinder, which have prescribed lengths and can be rotated and slided relatively, by each other. CONSTITUTION:A handle 5 is stuck to the other end of an inside cylinder 1 of a developer vessel whose one end a toner supply hole 2 with a cover 3 is stuck to. A guide ring 6 is truck to the other end of the inside cylinder 1. The inside cylinder 1 is incorporated rotatably in an outside cylinder 4. Mutual position relations between discharge apertures 1a and 4a of a developer, namely, a toner T which are provided on circumferential faces of the inside cylinder 1 and the outside cylinder 4 respectively and have lengths in the directions of the rotation axis are held by a click device or the like so that they are kept at an interval of 180. When a prescribed amount of the toner T is charged from the toner supply hole 2 into the developer vessel constituted in this manner and the vessel is closed by the developer sealing cover 3, the toner T is not flowed out neither floated at all during handling because discharge apertures 1a and 4a are placed apart from each other, and the vessel is very clean. |
