PURPOSE:To prevent deterioration of a photosensitive drum caused by the intrusion of light and dust by interrupting the intrusion of disturbance light and dust into a device main body. CONSTITUTION:A buffer body 200 having light shielding property is fitted to a part on which the upper casing 24 and the lower casing 25 are abutted, thereby blocking the space of the abutting part. At this time the outer peripheral edge of the buffer body 200 is made to protrude beyond an upper casing 24 and a lower casing 25. |
