PURPOSE:To replace easily and safely an image carrying body by constituting so that a cam provided in a frame body opens a movable part, and the image carrying body such as a photosensitive drum, etc. in a vessel is loaded into the frame body. CONSTITUTION:A photosensitive drum 3 is stored and held in a cylindrical space part of a vessel 21 formed by a fixed member 22 and both movable members 23, 24. When the vessel 21 is fitted into a frame body 19 from its upper part, projecting parts of projecting pins 30a, 30b are made to contact by pressing to a cam surface 31 of a front side plate 15 and a rear side plate 16, the pins 30a, 30b are pushed up, and when both movable members 23, 24 are opened, a supporting sorce of a journal part 3a by curved parts 29a, 29b is released, therefore, the drum 3 drops into the frame body 19 and is set. Subsequently, when the member 22 is drawn up, the opened members 23, 24 descend by its empty weight, and the pins 30a, 30b drop into notch parts 27a, 27b, therefore, both movable members are drawn up in a state that the opening state is held. Accordingly, the vessel 21 is drawn up without making both movable members contact with the surface of the drum 3. |
