った。For this reason, attempts have been made to make the transfer roller conductive and use the transfer roller itself as an electrode. However, even if the rubber material of the roller is made semiconductive, the primer used to bond it to the roll core is insulated. Since it is a body, sufficient conductivity cannot be obtained as a roller, resulting in insufficient transfer.
［発明の目的］
本発明はこのような欠点を解決するためになされたもの
