PURPOSE:To obtain a stable image free from density variance by moving a destaticizing lamp in the axial direction of the rotary shaft of a photosensitive body to suppress partial optical fatigue of the photosensitive body for a long period. CONSTITUTION:A destaticizing lamp 10 is attached to an angular shaft-shaped supporting rod 12 which is laid between side plates 11a and 11b, where a photo sensitive body 1 is laid, in parallel with the axis of the revolving shaft of a photosensitive body 1, and the supporting rod 12 is supported by bearing members 13a and 13b with angular holes fixed to side plates 11a and 11b freely slidably only in the axial direction, and a compression spring 14 between its projecting part and the bearing member 13b energizes the supporting rod 12 toward the projecting side. A bracket 15 connected to the side plate 11b is provided with a cam 17 turned around a shaft 16, and the cam 17 is rotated and driven to push and move the projecting front end part of the supporting rod 12 against the compression spring 14 and the supporting rod 12 and the destaticizing lamp 10 joined with this rod 12 integrally are moved back and forth in the axial direction of the rotary shaft of the photosensitive body 1. |
