摘要： A neutralizing mechanism is provided on at least one conveying path proximal member installed on a conveying path of a sheet material in a vicinity of a transfer position, and is grounded by using a conducting material. The neutralizing mechanism includes a neutralizing circuit that includes a resistor and a ground switch electrically connected in parallel to each other. The ground switch is turned off at least at a time of applying the transfer bias to prevent a leakage of a transfer current, and turned on for a predetermined time at a time other than the time of applying the transfer bias to earth and remove a static electricity from the conveying path proximal member.
