PURPOSE:To improve maintenance and reliability by providing a restraining means of restraining the rotation of a developing machine body by its input driving force and of holding a development roll and a drum at proper distance. CONSTITUTION:To a frame 2, the supporting member 3 of a developing machine body 1 is fixed, and the supporting member 3 is provided with a guide part 9 extending vertically and a bearing part 10 positioned at the lower end side of the guide part 9 and having an upward opening. Further, a restraining means A is provided to hold a development roll 5 and a photoreceptor drum 4 at proper distance, and this means A has a distance setting screw 6 screwed into the frame 2. The main body 1, having the development roll 5 and a main shaft 7, is moved down to mount the main shaft 7 on the bearing part 10 of the supporting member 3. In this state, the main body 11 is capable of rotating around the main shaft 7 supported on the bearing part 10. Thus, the structure is simplified, the maintenance is improved, and the reliability is also improved. |
