PURPOSE:To facilitate maintenance and inspection regarding to abrasion, etc., by connecting a rotary connection member which is fitted in the supporting shaft part of the detachment side of a rotary member with a sliding member which has a fixation relation with the supporting shaft in a sliding state. CONSTITUTION:On a photosensitive drum supporting shaft 1, photosensitive drum units 3, 4 and 5 are equipped, an electricity feeding device is equipped on the supporting shaft 1 until a bearing 2 and a base 8 collide against each other, and the connector 6 of the photosensitive drum 4 is connected to the connector 27 of the electricity feeding device side. After a clamping ring 30 is screwed up, a supporting plate 31 is fixed to the front side plate of a fitting device body and at this time, the collector 29 of the electricity feeding device is connected to the connector 33 of the supporting plate 31. When the photosensitive drum 4 rotates on the supporting shaft 1, the connectors 6 and 27 while connected together rotates together and the connectors 29 and 33 while connected are still as well as the supporting plate 31, so that electricity feeding is ensured by the slide contact between sliding plates 10 and 11 and sliding brushes 21 and 22. |
