<p>PURPOSE:To surely attract a sheet material in an electrostatical manner so as to hold and convey the sheet material without slipping the same, by providing a holding and conveying member made of inductive materials and a means for applying an alternate voltage to the holding and conveying member. CONSTITUTION:An alternating charge density pattern is formed on an outer surface of a holding an conveying member 2 made of inductive materials by a means for applying an alternate voltage to the holding and conveying member 2, and a position from which a sheet material 1 or the like is fed to the holding and conveying member 2, is set in a range where it can make contact with a counter electrode of a voltage applying means 5'. Accordingly, since the sheet material 2 such as an image-transfer sheet or the like which is inductive is fed to the holding and conveying member 2 within such a range that it can make contact with the counter electrode of the voltage applying means 5', it is attracted by a strong attraction force onto the holding and conveying member 2 under an uniform electric field and is held without slipping. Then, it is carried by the holding and conveying member 2.</p> |
