PROBLEM TO BE SOLVED: To prevent the occurrence of distortion of a developer replenishing path and prevent the developer concentration on a formed image from being unstabilized by providing ribs fastening the upper face and bottom face of the developer replenishing on the developer supply path. SOLUTION: The upper face 5 and the lower plate 25a of a toner replenishing path are fastened together at both end sections P in the width direction, and multiple ribs 30 supporting the upper face 5 and the lower plate 25a of the toner replenishing path are provided at uniform intervals in the longitudinal direction. If the upper face 5 and the lower plate 25a of the toner replenishing path are fastened at both end sections P only, the strength of the faces is weak, and the distortion of the toner replenishing path is easily generated by external force such as the force of the toner flowing inside. When the ribs 30 are provided, the upper face 5 and the lower plate 25a of the toner replenishing path can be prevented from being deformed by the external force, and the vertical interval of the toner path can be kept at the desired interval. The toner density can be prevented from being unstabilized by the distortion of the toner replenishing path. |
