PURPOSE:To obtain a transfer drum whose insulating and elastic threadlike member is not loosened when stress is added to a frame body of a photosensitive body, by extending the threadlike member between both frames of the photosensitive body, in a state that it is stretched in advance against its elasticity. CONSTITUTION:An elastic body which has performed insulation covering to rubber or a coil spring wound comparatively thinly is used for a constituent base material of a transfer paper supporting body, and the transfer paper supporting body 9 is constituted by extending this insulating and elastic threadlike member between both frames 5, 6 in a state that it is stretched in advance against its elasticity. As for the transfer drum, since that elastic force is energized in advance to the insulating threadlike member 8 itself, slackness of the threadlike member 8, which is generated when it is extended between both the frames 5, 6, and when the frame body is distorted is absorbed by its self-elasticity, by which there is no possibility that a function for pringing transfer paper into press-contact with a photosensitive body 1 is not damaged. |
