PURPOSE:To obtain a satisfactory image by confronting an image forming means with a photosensitive belt with high accuracy and keeping a set gap by abutting each gap holding member provided coaxially with the developing roller of each developing device with the side terminal part of a supporting body by pressing with an elastic member. CONSTITUTION:The supporting body fixed at a device main body so as to be inscribed with the photosensitive belt 1, i.e. a guide member 4 is provided. The photosensitive belt 1 is set at a stretched state by the dynamic function of a tension roller 5 an in upper direction, and the inner peripheral plane of the belt is slided with the guide member 4. Thereby, a photosensitive material on the outer peripheral plane of the photosensitive belt 1 can be always kept at a constant position against the surface of the guide member 4 even while it is carried, and a stable image forming plane can be comprised. |
