Abstract

Abstract A device applicable to a color copier (10) or the like for transferring an image to a paper sheet includes a hollow drum-­like frame (44) the peripheral wall of which is removed except for opposite circumferential edge portions (48a, 48b) and a connecting portion (48c) which links the edge portions to each other. A conductive sheet (46) is wrapped around the frame (44) to cover the removed portion of the frame. An intermediate portion of the conductive sheet (46a) is bulged radially outward beyond the outer periphery of the frame (44).
