PURPOSE:To obviate a supporting lever preventing a holding member from from falling by providing an engagement part which engages with the holding member of an electrostatic charger on a member for locking a photosensitive body and engaging the holding member in an erect state with the above- mentioned engagement part. CONSTITUTION:A photosensitive drum 1 and a belt charger 2, etc., are attached to a supporting frame 7 and they are drawn out along a guide rail 8. In the case of taking out the drum 1, the frame 7 is drawn out from a copying machine and the holding member 15 is turned upward so as to be erect. After the charger 2 is separated from the drum 1, the drum 1 is pulled out. In such a case, a hook lever 17 is turned to release the locking of the member 15 and the member 15 is made erect. Then, the engagement of a lock lever 12 with a lock pin 14 is released so as to make a lever 12 erect and the engagement part 12a of the lever 12 is engaged with the engaging groove 15c of the member 15, thereby preventing the member 15 from falling. |
