TRANSFER AND CONVEYANCE DEVICE

摘要

PURPOSE:To perform stable conveyance and secure transfer without any shift by passing a transfer material through between an electrostatically charged conveyor belt and a conductive member which is provided in front of a transfer position in contact with the belt and connected to an AC power source. CONSTITUTION:An endless belt 111 consists of a dielectric layer 112 as a surface contacting the transfer material 117 and a conductor layer 113 as its reverse surface and supports and conveys electrostatically a transfer material 117 which is a sheet type or continuous in the moving direction, a support roller 114 and a driving roller 115 supports an extend the belt 111 and conveys it in a constant direction at a constant speed and an electrostatic charger 116 charges the dielectric part 112 of the belt 111 electrostatically. Further, this device is equipped with a means which grounds or applies an optional bias to the conductor part 113 of the belt 111 and a means which supplies the transfer material 117 through between the charged belt 111 and the conductor rubber roller 118 connected to the AC power source 127 arranged in front of the transfer position in contact with the belt 111.
