Electrostatic holding and conveying apparatus
 An electrostatic holding and conveying apparatus having an endless belt member which comprises a base layer of soft, flexible insulative material and two groups of electrodes equally spaced and disposed on a first surface of the base layer. A protective layer of soft flexible semiconductive or insulative material is disposed on the first surface of the base layer to cover the electrodes. Two groups of terminals are provided on a second surface of the base layer and electrically connected to the two groups of electrodes, respectively. The endless belt extends between a drive roller and a driven roller with the second surface of the base layer in contact with the rollers. One of the rollers has two contact rings isolated from each other and supplied with a high DC voltage. The endless belt is driven by the drive roller with at least one terminal of each terminal group in electrical contact with the corresponding contact ring of the one roller so that the endless belt conveys sheet materials while electrostatically holding them.
