<p>PURPOSE:To carry a photosensitive body and a transfer sheet completely synchronously with each other, by driving one of them with a motor and attracting the other to one electrostatically to drive the other frictionally with one. CONSTITUTION:A photosensitive body 6 is stretched around freely rotatable rollers 7 to which a driving force is not applied, and a transfer sheet 10 is attracted electrostatically to a transfer sheet holding drum 13, which is driven by a motor 18, and is sent frictionally by the rotation of the drum 13. In this case, electrostatic attraction acts between the positively electrostatically charged insulating sheet 10 and the photosensitive body 6 superposed on this sheet 10 also, and the photosensitive body 6 is attracted to the sheet 10 and is moved. It is necessary that the torque of a torque motor 29 which driving a take-up roller for winding the transfer sheet 10 is made smaller than the frictional force generated between the drum 13 and the sheet 10. Thus, the photosensitive body and the transfer sheet are carried completely synchronously with each other to attain a picture without color slippage.</p> |
