PURPOSE:To remove electrode wearing foreign matter, generated between both electrodes, so as to prevent increase of contact resistance between the electrodes by providing the reciprocating electrode at least one part of which is always brought into sliding contact with a rotary electrode during a reciprocating process. CONSTITUTION:Even during rotation of a sensitized unit drum 1, each reciprocating electrode 26, 27 is not dislocated from but brought into sliding contact with each rotary electrode 8, 9 to supply power to a heater 7 from a power supply through the reciprocating electrodes 26, 27, rotary electrodes 8, 9, lead wires 10, 11, connectors 12, 13 and lead wires 14, 15. Here by parallelly reciprocating the reciprocating electrodes 26, 27 relating to a rotary shaft 2, carbon foreign matter, generated between the reciprocating electrodes 26, 27 and the rotary electrodes 8, 9, is removed. In this way, contact resistance between the reciprocating electrodes 26, 27 and the rotary electrodes 8, 9 can be prevented from increasing. |
