摘要： A device for driving a photoconductive drum (70) of an electrophotographic copier and others is operable without the need for gears, a toothed belt and other transmission mechanisms. An outer roller type drive motor (80) is interposed between the drum (70) and a drum support shaft (76) such that an outer wheel portion of the motor drives the drum by way of an engaging member. Those members with which the body of the motor and that of the copier are engaged are made of a vibration-damping material. Tapered portions which are axially movable into and out of contact with each other are provided in a drive transmitting section with which an output portion of the motor and one end of the drum are engageable. Pressing means (100) for causing one end of the drum into contact with the outer wheel portion of the motor through the tapered portions is provided at the other end of the drum.

摘要： 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).
