PURPOSE:To make the installation of a corona discharger to the inside of a drum form screen by spreading the photosensitive screen used in an electrophotographic method by ion current control to a drum form frame body and providing a driving power transmission part along the peripheral surface of the frame body. CONSTITUTION:A screen 7 is supported by a wheel body 82 having a driving gear 83 part and a wheel body 81 and the wheel body 82 is supported by a supporting member 9 via bearing member 10. The drum form screen 7 is rotated together with the wheel bodies by turning of the gear 16 (secured to the shaft 15 of a driving source) intermeshed with the gear 83. On the other hand, a corona discharger 14 is mounted to the rotating member 13 which is made turnable about a revolving shaft 12. At the time of installing the corona discharger, the rotating member 13 is first positioned in the upper part, then the corona discharger 14 is mounted to the guide rail 131 of the member 13 and the rotating member 13 is turned in the arrow direction to engage the guide member 17 to a click stop pin 10, whereby the corona discharger 14 is disposed in the specified position within the screen 7. |
